STMicroelectronics TSC2020 Bidirectional Current Sense Amplifiers

STMicroelectronics TSC2020 Bidirectional Current Sense Amplifiers are precision devices that sense current via a shunt resistor over a wide range of common-mode voltages, from -4V to +100V. The amplifiers sense very low drop voltages, minimize measurement error, and fully operate over a 2.7V to 5.5V supply voltage range and -40°C to +125°C industrial temperature range. TSC2020 components may be used for precision current measurement, overcurrent protection, current monitoring, and feedback loops.
