NCS210RSQT2G

NCS210RSQT2G is a bidirectional, zero-drift, low- or high-side current sensing, voltage output, current shunt monitor (also called current sense amplifier) that can measure the voltage across shunts at common-mode voltages from -0.3V to 26V, independent of the supply voltage. The low offset of the zero-drift architecture enables current sensing across the shunt with maximum voltage drop as low as 10mV full scale. This device can operate from a single +2.2V to +26V power supply, drawing a maximum of 80µA of supply current, and is specified over the extended operating temperature. Typical applications include current sensing (high-side/low-side), automotive, telecom, power management, battery charging, and discharging.
