Description
The TSC102 measures a small differential voltage
on a high-side shunt resistor and translates it into
a ground-referenced output voltage.
The device’s wide input common-mode voltage
range, low quiescent current and tiny TSSOP8
packaging enable use in a wide variety of
applications (also available in SO-8 package).
The input common-mode and power supply
voltages are independent. The common-mode
voltage can range from 2.8 to 30 V in operating
conditions.

The TSC102 is rugged against abnormal
conditions on the input pins: Vp and Vm can
withstand up to 60 V in case of voltage spikes, as
little as -16 V in case of reversed battery, and up
to 4 kV in case of electrostatic discharge.
In addition to the current sensing amplifier, the
TSC102 offers a fully accessible amplifier for
output signal conditioning.
The device’s overall current consumption is lower
than 420 µA.

TSC102 Application schematic and pin description
1 Application schematic and pin description
The TSC102 high-side current sense amplifier features a 2.8 to 30 V input common-mode
range that is independent of the supply voltage. The main advantage of this feature is that it
allows high-side current sensing at voltages much greater than the supply voltage (V

2. Human body model for Vm and Vp: a 100 pF capacitor is charged to the specified voltage, then discharged
through a 1.5 kΩ resistor between the Vp or Vm pin and Gnd while the other pins are floating.
3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 kΩ 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 Ω). 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.

6.5 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
=Av. V
a1-th
sense
The actual value is very slightly different, mainly due to the effects of the input offset voltage
V
and the non-linearity.
