STMicroelectronics TSC2021IYDT, Current Sensor IC 8-Pin, SO8

The STMicroelectronics Bidirectional current sense amplifier can sense current via a shunt resistor over a wide range of common-mode voltages, from -4 to +100 V, whatever the supply voltage is. It is able to sense very low drop voltages, minimizing measurement error. They may be used for various functions like precision current measurement, overcurrent protection, current monitoring, and feedback loops. These devices fully operate over the supply voltage range of 2.7 to 5.5 V, and over an ambient temperature range of -40 to 125 °C.
