HOLTEK’s New Series Gain WPC Certification

Holtek’s new BP66FW124x series has received WPC Wireless Charger Receiver Certification.

HoltekThis series of Holtek wireless charger receiver MCUs, the BP66FW124x, include a full range of functions such as an integrated high efficiency full-bridge synchronous rectifier circuit, an AM modulator, an LDO and a lithium battery linear charging management circuit.

All of these features combine to provide great reductions in required external circuitry. The abundant MCU resources together with suitable external components ensure that product development can be implemented according to individual product requirements.

The BP66FW124x series of devices have now passed the WPC latest version V1.2.4 certification. This certification includes communication protocol, power error calculation, power receiving calculation, and interoperability testing for Qi-certified transmitter products.

This reference design solution also provides a development board and a complete set of development data which enables designers to develop their products more rapidly and efficiently.
