Overview
The TSC1031IDT, produced by STMicroelectronics, is a high-voltage high-side current sense amplifier. This component measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. It is designed to operate in harsh environments with features such as adjustable gain and built-in EMI filtering. The TSC1031IDT is available in SO-8 and TSSOP-8L packages, making it suitable for a wide range of applications due to its low power consumption and compact size.
