Hi,
Currently we need to supply a 2S battery system using SND9039. There'll be a 5V buck to generate 5V as VSYS input to SND9039, but we still need to sense 2S battery voltage through VBATSENSE pin by internal GPADC. So, the questions are
- What is the suggested resisitive divider ratio and corresponding resistor values on VBATSENSE pin?
- Is there any concern that VBATSENSE and BUCK/LDO inputs are from "2S battery with resistive divider" and "fixed 5V from a buck" individually?
Thanks!
Antony
