Renesas IDTP9020

Description

The IDTP9020 is a highly-integrated single-chip WPC-compliantwireless power receiver IC. The device receives an AC powersignal from a compatible wireless transmitter and converts it intoa regulated 5V output voltage which can be used to powerdevices or supply the charger input in mobile applications. TheIDTP9020 integrates a high-efficiency synchronous full-bridgerectifier, high-efficiency synchronous buck converter, and controlcircuits used to modulate the load to transmit WPC-compliantmessage packets to the transmitter station to optimize powerdelivery. Power delivery is limited to 5W in accordance with theQi specification.The device includes over-temperature/voltage protection and aForeign Object Detection (FOD) method to protect the basestation and mobile device from over-heating in the presence of ametallic foreign object. Fault conditions associated with powertransfer are managed by the embedded MCU, which alsocontrols status LEDs to indicate operating and fault modes
