Overview
The TSC888AILT, produced by STMicroelectronics, is a low-cost high-side current sense amplifier. This device measures a small differential voltage on a high-side shunt resistor and translates 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, or 100 V/V. The TSC888AILT is packaged in a tiny SOT23-5 package, making it ideal for a wide variety of applications due to its wide input common-mode voltage range, low quiescent current, and flexible supply voltage range.
