GMPQ80XXA

3. FUNCTIONAL DESCRIPTIONS

QI Compliant wireless transmitter 1.0.3 Specification.

Conform the QI standard of version 1.0.3. QI system now supports up to 5W.

Strong Demodulation for QI packet

Demodulation is very import for QI transmitter. GPMQ80XXA uses flexible process to solve this problem. They have high performance at

demodulation.

Thermal Protection

The system will protect and show the alarm message when the thermal pin(p01) reach the alarm voltage.
