Description:

We are looking for an hardware designer to develop the charging circuit for a slim Wireless Qi powerbank. The discharge rate can be at 5W without fast charging support.

Charging circuit requirement:

- The design should accomodate battery protection circuit for Li-Ion polymer battery(3V cutoff, 4.2V max).

- The design should accomodate automatic Li-Ion polymer battery charding when the USB-C port is plugged in.

- The design could have an interface to another MCU to show charging status and battery capacity. The interface either analog or digital and can be suggested by designer.

- The design should charge Wireless Qi receivers once detected.

- The design should have Wireless Qi safety features like FOD.

- Design should be optimal for PCB area, less area and less height of components.

- The circuit should have a regulated output from battery for other electronics circuitory of 7.5V, 3.8V and 3.3V

- The circuit should have ultra low sleep current in the range of 10s of microamps when no charging/discharging powerbank functionality is active

- The wireless transmitter will be trigerred via external MCU

Battery specification:

- 0.5C charge and 0.5C discharge.

- No PCM

- No NTC

Output:

1. Schematic and technical document for design

2. BOM(including wireless charge pad) with estimated pricing for 1000 MOQ

3. 3D PCB area required for PCB

4. Cost optimized design
