General Description
Advanced high performance semiconductor devices can be sensitive to Single Event Latch-Up (SEL) effect
when exposed under radiation in the space environment. Even if SEL is a very rare event, it can lead to device
destruction. A safe design for a mission critical application shall include a protection device called the Latch-Up
current Limiter (LCL).
The 3DPM0168-2 LCL monitors the power supply line of the radiation sensitive device and switches it off
instantaneously in case of “radiation induced SEL”.
Featuring specific radiation effect mitigation techniques and utilizing space design derating rules, the Rad Hard
by Design 3DPM0168-2 LCL is an ITAR Free product and features a SEL/SET LETth of 80 Mev.cm2/mg and a
TID of 50krad (Si).
The 3DPM0168-2 is manufactured with 3D Plus Space Qualified stacking technology designed for high
reliability applications, and is available in a compact size and low weight 20-pins SOP package 1.27mm.

OFF state and load is disconnected from the Vin supply.
When connected to high level, LCL is started and load is
connected to the Vin supply.
This is an input pin.
Pin 2: ADJ_RESTART
Pin used to select the automatic restart function provided
by the LCL and to adjust the delay.

Current Limitation Setting
LCL has two current thresholds:
a low level current threshold to protect the load when it is in standby mode (Ith_stb).
a high level current threshold to protect the load when it is in run mode (Ith_run).
User selects the active threshold through the RUN/STB command.
Threshold values are set by the user through two resistors:
Rstb connected between LIM_STB and GND for standby current threshold.
Rrun connected between LIM_STB and LIM_RUN for run current threshold.
Rstb is function of the standby current threshold (Ith_stb) and input voltage value (Vin). Value is calculated
using the following formulae:

If we have Vin = 2.5V, Ith_stb = 200mA and Ith_run = 1200mA.
Equation (1) gives Rstb = 11.483kΩ. Selected standard value is 11.5kΩ (0.1%).
Equation (2) gives Req = 1.69kΩ and Rrun =1.983kΩ. Selected standard value is 2kΩ (0.1%).

Automatic Restart Setting
Automatic restart function allows the LCL to automatically reconnect the load to the input voltage supply after a
delay (Tdelay) in case of protection activation (load disconnected following detection of load current above the
active threshold). Delay is set by the user through a capacitor (Cdelay) connected between ADJ_RESTART and
GND.
Cdelay is calculated using the following formulae :
C delay  26  Tdelay (3)
Rem: For equation 3, Tdelay is in ms and Cdelay in nF.

If the defect will not disappear after a first deconnection/reconnection in the circuit to protect, protection is
activated again after a shorter delay (tdelay2 in the example).
If the defect is persistent, the following shorter delays will remain at the same value as the first short delay (tdelay2
in the example).
Tdelay2 is also function on the capacitor delay but limited in duration when Cdelay value increases (see curves

Resistor in Vaux line for auxiliary supply voltage greater than 5.5V
A shunt regulator is implemented on the auxiliary supply (Vaux) to limit the internal voltage which powers the
LCL internal circuits (Vbias).
Regulator is activated when bias voltage is greater than 4.5V and increases the current consumption on Vaux.
From 5.5V, an external serial resistor shall be added in the Vaux line to limit the auxiliary supply current and to
reduce internal LCL power dissipation.
Table below gives resistor value according to Vaux voltage range.

supply. It implements a serial switch and a shunt resistor for

current monitoring.
If a high energy particle hits the sensitive load and induces a
Figure 4 : Power Distribution scheme
Latch-Up, its supply current rises quickly. The LCL module
detects this abnormal current and disconnects instantaneously
the load from the supply. Additionally, any load decoupling capacitors are also quickly unloaded by the
integrated LCL parallel output switch to further limit energy dissipation at load level.
LCL module offers two current limitation thresholds. A low level current threshold called “I threshold Standby”
(Ith_stb) and a high level current threshold called “I threshold run” (Ith_run). Ith_stb should be selected when
load is in low consumption mode (standby). Ith_run should be selected when the load is in normal or run mode.
Active threshold level is selected by an external command (RUN/STB).
Threshold currents are adjustable by the user through two external resistors. Rstb connected between LIM_STB
pin and GND pin to define the standby current threshold. Rrun connected between LIM_RUN pin and LIM_STB
pin to define the run current threshold.
When the active threshold is reached, load is disconnected from the input supply and the protection status is
activated to warn the system that the LCL module has trigged its current protection. LCL behaviour at this stage
is function of the automatic reconnection mode selection.
If automatic reconnection mode is not selected (ADJ_RESTART pin connected to GND), LCL stays in OFF
State. To reconnect the load to its supply voltage, ON/OFF command shall be put in OFF state (low level) and
then brought again to the ON state (high level). This OFF and ON command cycle reset the Protection status.
If automatic reconnection mode is selected (ADJ_RESTART pin connected to a capacitor - Cdelay), LCL stays
in OFF state for a duration function of Cdelay capacitor value. After this duration, LCL is automatically
switched OFF and ON again. The load is reconnected to its supply voltage. Protection status is reset at the same
time.
If a new over-current is detected, LCL switch OFF again for a new time delay and then reconnect the load to its
supply voltage automatically.
LCL can also be used to switch ON and OFF the load
thanks to the ON/OFF command.
When commanded ON, voltage at LCL module level rises
slowly to limit inrush current from the load supply and
avoid tripping the LCL current protection.
When commanded OFF, the internal LCL serial switch is
switched OFF smoothly and the internal output parallel
switch is not activated. The output voltage profile is
function of the load behaviour and of the additional
decoupling capacitor.
LCL is designed to accept a maximum output decoupling
capacitor of 10µF and implement internally a capacitor of
220nF. Higher decoupling capacitor value may prevent the
LCL to be switched ON properly.
Figure 5 : Behaviour at ON command
A free wheeling diode is also implemented at LCL module output to allow disconnection of inductive load. Free
wheeling is implemented to protect the LCL module.

Block Diagram
LCL Block diagram is given in Figure 6.
Main switch to connect or
disconnect the load is a P channel
MOSFET. Parallel output switch
used to unload output decoupling
capacitor is a NPN bipolar transistor.
2.2µF
filtering
capacitor
is
integrated into the module at LCL
input and 220nF at LCL output. A
free wheeling diode is also
implemented to switch OFF
inductive load.
P channel MOSFET is driven from a
negative supply provided by a
charge pump circuit. This circuit is
powered from auxiliary voltage
through a shunt regulator.
Figure 6: LCL Block Diagram
Load current is measured through a shunt. A current comparator checks if the load current is higher or lower
than a reference current (current threshold) provided by the Ref. generation bloc. If current is higher than the
threshold, a stop command is sent to the State management block which initiates a switch OFF sequence.
Reference current provided by the Ref. generation block is adjusted by the two resistors Rrun and Rstb (which
set respectively Ith_run and Ith_stb). The issued reference current is function of the RUN/STB command.
State management block drives the serial and parallel switches and generates the Protection Status signal. State
management block also decides to restart automatically the LCL, after current protection activation, if automatic
reconnection mode is selected. Delay for automatic reconnection is set by Cdelay value.
ON/OFF interface monitors the ON/OFF signal to start or stop the LCL. When LCL is started, charge pump
circuit is activated. At LCL start, state management is also reset to clear any fault condition.
Over-Current Protections
Behaviour of the LCL in case of short circuit event is
detailed in this section. The short circuit event can be
assimilated to a latch-up event applicable to a sensitive load.
Plot in Figure 7 shows the LCL response to an output short
circuit. At short circuit application, output current rises and
output voltage decreases. After the response time delay,
LCL is switched OFF and output voltage falls quickly.
Output current is going down at the same time.
LCL response time is impacted by the decoupling capacitor
at module output. LCL can tolerate up to 10µF but
maximum response time of 10µs is guarantee if output
capacitor is limited to 7µF.

Hi-Rel Latch-Up Current Limiter (LCL)
High Input Voltage Range, 2A Output Current
Radiation Hardened Design
Figure 8 : Behaviour at short circuit application
When a short circuit is detected by the LCL Module, output
is disconnected. If automatic reconnection mode is selected,
LCL module reconnects the load to its supply voltage after a
delay defined by Cdelay capacitor value. This behaviour is
illustrated in Figure 8.
Delay for automatic reconnection is set to 8.5ms. After 8.5ms
(Tdelay1), LCL tries to reconnect the load to its supply. As
long as short circuit is present, load is disconnected again and
a new cycle restarts after 6.5ms (Tdelay2, as described in
section “Automatic Restart Setting”). This process continues
up to short circuit removal.
Low duty cycle operation (short ON time, long OFF time)
allows limiting internal heating to non critical value for
module reliability. This mode can be used during all product
life without module reliability reduction.
When the short circuit is removed, load is reconnected to its
supply voltage and can continue its normal operation. This
behaviour is illustrated in Figure 9.
If automatic reconnection mode is not selected, LCL module
stays OFF after over-current detection. An OFF then an ON
command cycle is needed to restart the LCL and clear the
fault.

Layout Recommendations
Critical event for LCL module is load disconnection in case of over-current event (load in Latch-up). In this
case, high di/dt are experienced at module input and output.
Impedance at LCL module input shall be maintained low. Module shall be mounted close to the voltage source
or properly decoupled by capacitors connected between VIN and GND (TES low ESR tantalum capacitors from
AVX or T530 tantalum capacitor from KEMET are recommended). These capacitors shall be mounted closely to
the module VIN and GND pins. It is also recommended to use copper planes for both VIN and GND or at least
large conductor traces with minimum loop area. If resonances may occur between the decoupling capacitors and
the parasitic inductance between the module and the Vin voltage source, they have to be damped (serial RC
circuit between module and ground).
Inductance between LCL module output and load shall be maintained low to avoid negative voltage at module
output during load disconnection. Again copper planes are recommended or large conductor traces with local
decoupling capacitor at load level (they shall not exceed 10µF). If load has an inductive part, and is sensitive to
negative voltage, a free wheeling diode shall be added at load level (free wheeling diode integrated at module
may not be sufficient to limit negative voltage value).
