Overview
The TSC101BILT, produced by STMicroelectronics, is a high-side current sense amplifier designed to measure a small differential voltage on a high-side shunt resistor and translate it into a ground-referenced output voltage. The gain of the amplifier is internally fixed, available in three different gain options: 20 V/V, 50 V/V, and 100 V/V. This component is notable for its wide input common-mode voltage range, low quiescent current, and compact SOT23 packaging, making it suitable for a variety of applications.
