Texas Instruments  BQ500100DCKT

The bq500100 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 0 V to 20 V, independent of the supply voltage. The device features a fixed voltage gain of 50 V/V with a maximum gain error of 2% and a offset voltage of 150 µV (maximum).

This device operates from a single 2.7-V to 6-V power supply, drawing a maximum of 100 µA of supply current. The device is specified from –40°C to +105°C and is offered in the SC70 package.
