Richtek RT1650BWSC-2

Беспроводной приемник питания8 мА4 В ~ 10 В

Overview

The RT1650BWSC-2 is a wireless power receiver compliant with WPC V1.1 standard. The RT1650BWSC-2 integrates a synchronous full-bridge rectifier, a low dropout regulator, and a Micro Controller Unit (MCU) for control and communication. The device receives AC power from a WPC compatible wireless transmitter and provides output power up to 7.5W, which could be used as a power supply for a charger of mobile or consumer devices. The MCU-based controller can support bi-direction channel communication including Frequency Shift Keying (FSK) demodulation for power signal from the transmitter and Amplitude Shift Keying (ASK) modulation for power signal to the transmitter. The RT1650BWSC-2 provides Foreign Object Detection (FOD) function to meet the requirement after WPC V1.1. It communicates with the transmitter for the received power to determine if a foreign object is present within the magnetic interface. This provides a higher level of safety. The RT1650BWSC-2 provides a programmable dynamic rectifier voltage control function to improve power efficiency, a programmable power management control for maximum power delivery, a programmable current limit for suitable load setting, a programmable temperature setting with external NTC for thermoregulation, and proper protection functions such as UVLO, OVP, and OTP.
