Description
The TSC102 measures a small differential voltage
on a high-side shunt resistor and translates it into
a ground-referenced output voltage.
on a high-side shunt resistor and translates it into

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 SO8 package).

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.
