关键特性

应用

WP9005 is a high-efficiency, Qi-compliant wireless power receiver and a DC-DC charger providing power up to 7W for applications of cellphones and handset, etc. Using magnetic inductive charging technology, the wireless power receiver converts an induced AC magnetic power signal from a resonant tank to a programmable regulated DC power. A highly integrated low RDS synchronous rectifier and a highly sophisticated battery charger together offer a high efficiency and smart power management making WP9005 ideally suitable for battery-operated applications.

WP9005 includes an 8051-microprocessor offering a high level of programmability. WP9005 features a external current limit setting and a smart auto over-voltage protection scheme eliminating overcurrent overvoltage for extreme safe solutions in battery applications.

WP9005 is available in small QFN-4*4 20pin package, and it is rated for a -20 to 105°C ambient operating temperature range.
