Tool/software:
Dear experts,
I'd like to request a review of the schematic underneath. We intend to use it like this;
- Apply an ESD protected 5V from a DC charger (no USB-data pins).
- Use the PMID output for a 3W audio amplfier that must work when charger is connected and disconnected.
- Use the VSYS voltage for a 3.3V LDO with input voltage maximum of 5.5V that powers a micrcontroller and other parts.
- Get notified by the interrupt pin when charger is disconnected and connected.
- Read battery voltage through I2C.
SCL and SDA are pulled high through a 2K7 elsewhere. 3.3V is supplied by the LDO which is fed directly by VSYS.
Best regards and thanks in advance,
Jochem
