RAA458100GNP / RAA457100GBM Low Power Wireless Charging System Configuration and Function
RAA458100 / RAA457100 are power control IC for wireless charging. RAA458100 / RAA457100 are suitable for small capacity Li-ion secondary battery charging and various battery charging systems can be constructed by some function setting pins.
To adjust transmission power automatically, and to set battery charging parameters (RAA457100 register) from a transmitter system can be realized by bi-directional wireless communication function implemented in RAA458100 / RAA457100. Also, register accessing to a main device (RxMCU) in a receiver system can be performed from a main device (TxMCU) in a transmitter system. This document describes some wireless charging system configuration examples, the wireless communication function and the automatic transmission power control function.
