Overview

Description

The RAA458100 is wireless charging system transmitter IC for low power applications. When RAA457100 is used in a receiver, a wireless charging system with bi-directional communication can be constructed.

Features

  • Three operation modes which are available for various applications ATPC(AuTomatic Power Control) Mode , MCU Control Mode , Stand Alone Mode
  • Gate drive output for MOSFET bridge circuit : half bridge or full bridge is selectable
  • Over current protection for bridge circuit (OCP), Over temperature protection (THM), and various protection functions
  • Monitoring input voltage or current of bridge circuit and thermistor voltage (Temperature) by 12bit A/D convertor
  • Modulation/Demodulation function for bi-directional communication between transmitter and receiver
  • RAA457100 registers can be set by bi-directional communication from RAA458100 (ATPC Mode)
