Description

TSC2020, TSC2021 and TSC2022 are a series of precision bidirectional current

sense amplifier. They 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.

TSC2020, TSC2021 and TSC2022 are current sense amplifiers that 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.
