Hi Sendhil,
- Yes, this is doable, you can verify by utilizing the GUI and with an evaluation board.
- I advise caution for 4S w/ 5A charge current, ensure you size components appropriately for safety and set the registers configuration with close attention to protections. UV/OVP/OCP/OTP and input threshold.
- This device is capable of operating standalone (without HOST or PD Controller), however please ensure that you test the range of operation for your unique application.
Best,
Nouman
