Product Description

Reference for wireless charging instructions
Product Description:
YL_5W_Rev1.4 is a wireless charging transmitter, compatible with WPC Qi v1.2.4
latest standards, supports A11 or A11a coils, supports 5 Apple 7.5 W 、 Samsung 10
W charging. the internal integrated chip IP6806 detects a wireless receiver by
analog ping and establishes communication with the receiver, then the power
transmission begins. IP6806 decode the communication packets sent from the
receiver, then use the PID algorithm to change the oscillation frequency to adjust
the output power on the coil. terminate the power transmission once the battery on
the receiver is charged. The full-bridge drive circuit and full-bridge power MOS,
voltage & current ASK communication demodulation module are integrated.
