HL6101 is a fully integrated single-chip wireless charging power receiver IC that automatically detects and self-configures to work with WPC V1.2(Qi) and Air Fuel (resonant and inductive) standards. It integrates a high-efficiency full-synchronous rectifier and a high-performance switching regulator to deliver a maximum of 15W and 4-12V programmable output voltage. It offers with best-in-class conversion efficiency, minimum PCB footprint, as well as maximum design flexibility between receiving coil design and output voltage regulation to match down-stream Li-Ion battery charge ICs. This IC maximize charging efficiency by optimizing the full-synchronous rectifier’s operating condition based on the detected receiving mode, and adopting a high-efficiency switching post-regulator instead of the conventional low drop-out regulator (LDO). This configuration maintains high power conversion efficiency over a wide range of Vrect and Vout combination.

This IC enables multi-mode wireless charging receiver solution that works with both inductive and resonant transmitters to offer a transparent user experience. It also integrates comprehensive protection against input over-voltage, output over-load, over temperature and other abnormal conditions to guarantee safe operation under all application usage scenarios. HL6101 is available in a 64-bump, 0.4mm pitch, Wafer-Level Chip-Scale package (WLCSP), or a 32-pin 5mmx5mm QFN package.

HL6101 is suitable for a variety of wireless charging applications with 1-2s Li-Ion Battery. This includes mobile devices like smart phones, tablets and laptops, power banks and other accessories.
