Overview
The TSC101AILT, produced by STMicroelectronics, is a high-side current sense amplifier designed to measure small differential voltages on a high-side shunt resistor and translate them into a ground-referenced output voltage. This amplifier features an internally fixed gain and is packaged in a compact SOT23-5L package. The device is suitable for a wide range of applications due to its wide input common-mode voltage range, low quiescent current, and independent supply and input common-mode voltages.
