20-V, High-Side Current Sensor for Wireless Charging
1 Features 3 Description 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 ОјV (maximum). 1 Wide Common-Mode Range: 0 V to 20 V
Offset Voltage: В±150 ОјV (Maximum)
– Enables Shunt Drops of 10-mV Full-Scale
Accuracy: В±2% Gain Error (Maximum
Overtemperature)
Fixed Gain: 50 V/V
Low Quiescent Current: 100 ОјA (Maximum)
Small Package: SC70 This device operates from a single 2.7-V to 6-V …
