Richtek Technology RT1650
RT1650
Wireless Power Receiver Compliant with WPC
General Description
The RT1650 is a wireless power receiver compliant
with WPC V1.1 standard. The RT1650 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
RT1650 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 RT1650 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.
