Description
The VND5E008MY-E is a double channel highside driver manufactured using
STMicroelectronics® proprietary VIPower® M0-5
technology and housed in PowerSSO-36
package. The device is designed to drive 12 V
automotive grounded loads, and to provide
protection and diagnostics. It also implements a
3 V and 5 V CMOS compatible interface for the
use with any microcontroller.
The device integrates advanced protective
functions such as load current limitation, inrush
and overload active management by power
limitation, overtemperature shut-off with auto
restart and overvoltage active clamp. A dedicated
analog current sense pin is associated with every
output channel providing enhanced diagnostic
functions including fast detection of overload and
short-circuit to ground through power limitation
indication and overtemperature indication.
The current sensing and diagnostic feedback of
the whole device can be disabled by pulling the
CS_DIS pin high to share the external sense
resistor with similar devices.

2. Valid in case of external load dump clamp: 40V maximum referred to ground. The protection strategy
allows PowerMOS to be cyclically switched on during load dump, so distributing the load dump energy
along the time and to transfer a part of it to the load.

Note:

3.1
Load dump protection
Dld is necessary (Voltage Transient Suppressor) if the load dump peak voltage exceeds the
VCCPK max rating. The same applies if the device is subject to transients on the VCC line
that are greater than the ones shown in the ISO 7637-2: 2004(E) table.
3.2
MCU I/Os protection
When negative transients are present on the VCC line, the control pin is pulled negative to
approximately -1.5 V. ST suggests to insert a resistor (Rprot) in line to prevent the
microcontroller I/O pins from latching-up.
The value of these resistors is a compromise between the leakage current of microcontroller
and the current required by the HSD I/Os (input levels compatibility) with the latch-up limit of
microcontroller I/Os.
Equation 1
-VCCpeak / Ilatchup ≤ Rprot ≤ (VOHμC - VIH) / IIHmax
Calculation example:
For VCCpeak = - 1.5 V; Ilatchup ≥ 20 mA; VOHμC ≥ 4.5 V
75 Ω ≤ Rprot ≤ 240 kΩ.
Recommended values: Rprot =10 kΩ, CEXT =10 nF.

Application information
Current sense and diagnostic
The current sense pin performs a double function (see Figure 30: Current sense and
diagnostic):
•
Current mirror of the load current in normal operation, delivering a current
proportional to the load one according to a known ratio KX.
The current ISENSE can be easily converted to a voltage VSENSE by means of an
external resistor RSENSE. Linearity between IOUT and VSENSE is ensured up to 5V
minimum (see parameter VSENSE in Table 7: Current sense (8 V < VCC < 18 V)). The
current sense accuracy depends on the output current (refer to current sense electrical
characteristics Table 7: Current sense (8 V < VCC < 18 V)).
•
Diagnostic flag in fault conditions, delivering a fixed voltage VSENSEH up to a
maximum current ISENSEH in case of the following fault conditions (refer to
Table 10: Truth table):
–
Power limitation activation
–
Overtemperature
A logic level high on CS_DIS pin sets at the same time all the current sense pins of the
device in a high impedance state, thus disabling the current monitoring and diagnostic
detection. This feature allows multiplexing of the microcontroller analog inputs by sharing of
sense resistance and ADC line among different devices.
