Scheme introduction:
TIDA-00334 wireless power transmitter designed by TI is a small design application using bq500212A IC, which is suitable for low-power wearable devices. The voltage of the input unit from the micro USB interface is 5V. The low power design will support receiver output power up to 2.5W.
All key transmitter circuits are arranged in a 30mm area, which is consistent with the diameter of Wurth coil P/N 760308101103. The area is slightly larger than 25 cents or 2 euro coins. The size of PCB is 38mm X 76mm (1.5 "X 3.0"), and the circuit area is about 700mm2, which is located inside the coil with a diameter of 30mm.
Scheme advantages:
Small solution size: the diameter of the circuit area is about 30mm (the area is about 700mm2) -- PCB 38mm X 76mm
Common USB can input 5V working voltage
Meet Qi standard
Industry classification: intelligent wear
