STMicroelectronics TSC213

TSC213 is a zero-drift current sense amplifier that can sense current via a shunt resistor over a wide range of common-mode voltages from -0.3 to +26 V, whatever the supply voltage is. The TSC213 is designed with a specific zero-drift architecture, which can achieve high precision. TSC213 is a current sense amplifier that may be used in various functions such as precision current measurement, over current protection, current monitoring, feedback loops. It fully operates over the broad supply voltage range of 2.7 to 26 V and over the industrial temperature range -40 to 125 °C.
