The Texas Instruments BQ51013AYFPT is a Qi-compliant wireless power receiver IC designed to convert AC power from a transmitter coil into a regulated DC output for charging or powering portable devices. Its 1.5A supply current rating tells you the maximum load it can deliver to the downstream charger or system rail — enough for a typical 5W to 7.5W wireless charging application, depending on the rectifier efficiency and coil coupling. The 4V to 10V input range covers the rectified output from a standard Qi transmitter pad under most coupling conditions, so you don't need an external pre-regulator for common use cases.
Package and temperature — layout and environment check
Housed in a 28-DSBGA (0.4 mm pitch, 2.4 mm × 2.9 mm body), this part demands a clean PCB layout with proper decoupling close to the BGA balls — the small footprint saves board area but makes manual rework tricky without a hot-air station and stencil.
