STMicroelectronics‘ TSC1021 is a high-side current sense amplifier that measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. As a single-chip high-side current-sense amplifier, ST's TSC1021 simplifies the design of accurate measurement circuitry in electronic control units. The new device is available at distributor Rutronik now.

In addition to numerous consumer and automotive opportunities, the TSC1021 with AEC-Q100 automotive qualification will also be chosen for smart power management in equipment such as wireless base stations and computer servers. It provides a common-mode operating range of 2.8V to 30V and the device can withstand an outstanding range of -32V to +60V on its input pins without damage. The output voltage drift is 100ppm/°C maximum on the full temperature range of -40°C to 125°C. The input offset drift is 8uV/°C maximum on the full temperature range. The overall current consumption is under 300uA. In addition to its more focused common-mode voltage range, the TSC1021 benefits from high temperature stability, as well as high immunity to electromagnetic interference (EMI) thanks to its built-in filtering. These features will safeguard performance in industrial and automotive environments, and permit use in equipment such as accurate positioning mechanisms and safety systems including use in automotive such as window control, electric doors and seats, cooling fan and fuel pump applications.
