The TC7764WBG supports a maximum power output of 5 W and is compliant with the Qi standard’s low-power specification V.1.1.2, defined by the Wireless Power Consortium (WPC).

Toshiba has optimized the circuit design of the TC7764WBG to achieve a maximum power conversion efficiency of 95% (excluding the influence of the power signal receiving coil and tank capacitor). This enables mobile devices to be charged wirelessly as fast as if they were connected to a cable charger.

To ensure mobile device safety, the IC integrates a Qi protocol authentication circuit for power transfers, foreign object detection functions, under-voltage lockout (UVLO) and over-voltage lockout (OVLO) functions for the external power supply bypass option as well as thermal shutdown functions (TSD).

The TC7764WBG is housed in a WCSP28 package measuring 2.4 x 3.67 x 0.5 mm.
