The RT1652 is a wireless power receiver compliant with WPC Low Power v1.2 standard. The RT1652 integrates a synchronous full-bridge rectifier, a low dropout regulator, and a logic controller for control and communication. The device receives AC power from a WPC compatible wireless transmitter and provides output power up to 5W, which could be used as a power supply for a charger of mobile or consumer devices. The RT1652 output can also connect to Li+ battery directly, the direct charge mode features on running battery charger profile (PreCharge/CC/CV), to simplify the charging function design and improve the overall charging efficiency.<br /><br />The logic controller can support bi-direction channel communication including amplitude shift keying (ASK) modulation for power signal to the transmitter. The RT1652 provides Foreign Object Detection (FOD) function to meet the requirement after WPC V1.2. 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.<br /><br />The RT1652 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.
