TSC2020IDT

TSC2020IDT is a precision, bidirectional current sense amplifier. It can sense current via a shunt resistor over a wide range of common-mode voltages, from -4 to +100V, whatever the supply voltage is. It is able to sense very low drop voltages, minimizing measurement error. It is a current sense amplifier that may be used for various functions like precision current measurement, overcurrent protection, current monitoring, and feedback loops. Application includes high-side/low-side current sensing, battery management system, 48V power distribution, 48V power tools, motor control, automotive.
