Renesas Electronics Corporation Power Management - Specialized P9225-RAHGI

The P9225-RAHGI is a dual-mode wireless power receiver designed for applications requiring up to 5W of power. It supports both WPC and PMA protocols, utilizing magnetic inductive charging technology to convert AC power signals into a regulated DC output voltage ranging from 4.5V to 5.5V. The device features a low RDSON synchronous rectifier and an ultra-low dropout linear regulator, ensuring high efficiency, which is particularly beneficial for battery-operated devices. This receiver integrates a 32-bit ARM Cortex-M0 microprocessor, providing a high level of programmability. It includes features such as a programmable current limit and a patented over-voltage protection function, which reduces the need for additional external capacitors, thereby minimizing component count and cost. The P9225-RAHGI is housed in a compact 52-WLCSP package and operates within an ambient temperature range of 0¬8C to 85¬8C. Typical applications include headsets, tablets, digital cameras, and medical devices.
