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
- 0.5C charge and 0.5C discharge.
- No PCM
- No NTC
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
