The MAX17303 uses a charge-pump to drive the high-side protection FETs. If the protection feature is not required, then the charge-pump and protection FETs may be bypassed. Below is the hardware/firmware configuration to properly disable the charge-pump and protection FETs.
Disable Protection:
- Short CP to BATT pin
- Short CHG to BATT pin
- Connect DIS pin to GND via 1MOhm resistor
- Clear the enProt bit in the nNVCfg1 register (i.e. enProt = 0)
