STMicroelectronics TSC102
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.| Part No. | TSC102 |

DESCRIPTION
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.
