bq500100 Wireless Charging Current Monitor

Texas Instruments bq500100 Wireless Charging Current Monitor is a voltage output, current-shunt monitor for wireless charging to facilitate foreign object detection (FOD). This device can sense drops across shunts at common-mode voltages from 0V to 20V, independent of the supply voltage. The device features a fixed voltage gain of 50V/V with a maximum gain error of 2% and an offset voltage of 150µV (max.). This device operates from a single 2.7V to 6V power supply, drawing a maximum of 100µA of supply current. The Texas Instruments bq500100 is specified from –40°C to +105°C and is offered in the SC-70 package.
