Specifications

enters the power transmission stage, a metal foreign body entering the charging area will be
recognized. The transmitter will self-lock until the receiver moves away, and the charger will
automatically resume its normal working state.
3.4 Over-Voltage Protection
The QI transmitter has the function of over-voltage protection. When the DC voltage of
the transmitter exceeds a certain value (9.7V), the transmitter will stop working in time to
protect the circuit safety. Once the voltage drops to the allowable operating range (9.5V),
the transmitter will automatically return to its normal operating state.3.5 UVLO
3.5 UVLO
The Qi transmitter has the function of under-voltage protection. When the DC voltage
of the transmitter is lower than a certain value (4.3V), the transmitter will stop working, so as
to protect the components and chips from damage. When the voltage is restored to the
allowable operating range (4.4V), the transmitter will automatically resume its normal
working state.
