TSC199A3ICT

TSC199A3ICT is a zero-drift current sense amplifier that can sense current via a shunt resistor over a wide range of common-mode voltages from -0.3V to +26V, whatever the supply voltage is. TSC199 is designed with specific zero-drift architecture, which can achieve high precision. TSC199 is able to sense very low drop voltages, as low as 10 mV full scale, minimizing measurement error. TSC199 may be used in various functions like precision current measurement, overcurrent protection, current monitoring, and feedback loops. Applications include notebook computers, telecom equipment, industrial applications, power management, and battery chargers.
