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.

CIRCUIT060035 — Bidirectional current sensing with a window comparator circuit

This bidirectional current sensing solution uses a current-sense amplifier and a high-speed dual comparator with a rail-to-rail input common mode range to create over-current (OC) alert signals at the comparator outputs (OUTA and OUTB) if the input current (IG1) rises above 100 A or falls below (...)

CIRCUIT060037 — Precision over-current latch circuit

This high-side, current sensing solution uses a current sense amplifier, a comparator with an integrated reference and a P-channel MOSFET to create an over-current latch circuit. When a load current greater than 200 mA is detected, the circuit disconnects the system from its power source. The (...)
