BQ501210RGCR

The BQ501210RGCR by Texas Instruments is a digital controller designed for wireless power transmission, compliant with the Wireless Power Consortium (WPC) v1.2 standard. This device enables the wireless transfer of power to WPC-compliant receivers, with a capability of delivering up to 15W.

Key features include a 12-V to 19-V input voltage range, fixed frequency operation, and a rail voltage control architecture. It supports faster charging times and is backward compatible with existing 5-W WPC receivers. The device incorporates enhanced Foreign Object Detection (FOD) to detect metal objects prior to power transfer and offers low standby power during idle or charge complete states.

Designed for surface mount, the BQ501210RGCR comes in a 64-VQFN (9x9 mm) package. It operates within an ambient temperature range of -40°C to 85°C and requires a supply voltage typically between 3V to 3.6V, drawing a current of 52mA.

This intelligent controller manages the power transfer process by periodically pinging for devices, detecting foreign objects, monitoring communication from the receiver, and adjusting power accordingly. It also handles fault conditions and controls status indicators.
