Description
The TSC1031 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The TSC1031’s dedicated schematic eases the implementation of EMI filtering in harsh environments. The gain is adjustable to 50 V/V or
100 V/V by a selection pin.
Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications.
The input common-mode and power supply voltages are independent. The common-mode voltage can range from 2.9 to 70 V in the singlesupply configuration or be offset by an adjustable voltage supplied on the Vcc- pin in the dualsupply configuration.
With a current consumption lower than 360 μ A and a virtually null input leakage current in standby mode, the power consumption in the applications is minimized.

Application schematic and pin description
Application schematic and pin description
The TSC1031 high-side current sense amplifier can be used in either single- or dual-supply mode. In the single-supply configuration, the TSC1031 features a wide 2.9 V to 70 V input common-mode range totally independent of the supply voltage. In the dual-supply range, the common-mode range is shifted by the value of the negative voltage applied on the Vcc- pin. For instance, with Vcc+ = 5 V and Vcc- = -5 V, then the input common-mode range is
-2.1 V to 65 V.

3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
4. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of connected pin combinations while the other pins are floating.
5. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to ground.

5.6 Output voltage accuracy
The output voltage accuracy is the difference between the actual output voltage and the theoretical output voltage. Ideally, the current sensing output voltage should be equal to the input differential voltage multiplied by the theoretical gain, as in the following formula.
V out-th
= Av. V sense
The actual value is very slightly different, mainly due to the effects of:
the input offset voltage V os
,
the non-linearity.

The current from the supply flows to the load through the R sense drop equal to V sense
across R sense
resistor causing a voltage
. The amplifier’s input currents are negligible, therefore its inverting input voltage is equal to V m
. The amplifier's open-loop gain forces its non-inverting input to the same voltage as the inverting input. As a consequence, the amplifier adjusts current flowing through R g1
so that the voltage drop across R g1
exactly matches V sense
.
Therefore, the drop across R g1
is:
V
Rg1
= V sense
= R sense
.I

If I
Rg1
is the current flowing through R g1
, then I
Rg1
is given by the formula:
I
Rg1
= V sense
/R g1
The I
Rg1
current flows is multiplied by a ratio K2 and the resulting current flows into resistor
R g3
. Therefore, the voltage drop on the R g3
resistor can be calculated as follows.

The voltage across the R g3
resistor is buffered to the Out pin by the voltage buffer, featuring a gain equal to 2. Therefore V out
can be expressed as:

Application information TSC1031
The current multiplier gain K2 can be set to 2.5 or 5 depending on the voltage applied on the
SEL pin.
Since they define the full-scale output range of the application, the R sense
resistor and the amplification gain Av are important parameters and must therefore be selected carefully.
The TSC1031’s dedicated schematic eases the implementation of EMI filtering in harsh environments. A simple filter is described in
Figure 22 , where the input filtering is performed
by R f1
, R f2
and C f
. For more details concerning input filtering, please refer to application note AN4304 "How to filter the input of a high-side current sensing".
The values of R f1
and R f2
should be equal so as to balance the contribution on both amplifier inputs. The value of the C f
capacitor should be selected so that the cut-off frequency of the first-order low-pass filter provides enough attenuation to the high frequency interferences.
To balance the contribution of R f1
and R f2
in the current sense amplifier gain, an output resistor R f3
should be connected between pin A1 and Gnd. The value of R chosen according to the following formula.
f3
should be
K1 = 10 = R g3
/R g1= Rf3/Rf1
= R f3
/R f2
Please refer to application note AN4369 "Adjustable gain with a current sensing" for details concerning the influence of additional resistances.
