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 SO8 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.
