• Precision current sources
• Uninterruptible power supplies
• High-end power supplies

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.
