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. ST achieves a lower cost than existing devices by leveraging its own high-voltage manufacturing process. Applications include consumer and automotive as well as smart power management in equipment such as wireless base stations and computer servers.
