Optimizing usage for low power consumption
In order to reduce power consumption, Short-circuit, Discharge High-current and Discharge
Over-current Protection are automatically deactivated when the D-FET is disabled. The Charge
Over-current and Charge High-current Protection are disabled when the C-FET is disabled. Note
however that Charge Over-current Protection and Charge High-current Protection are never
automatically disabled when the chip is operated in DUVR mode.
Also note that none of the current protections are deactivated by the External Protection Input.
To save power during an External Protection event, DFE and CFE in the FCSR register should
be cleared and make sure that the chip is not operating in DUVR mode.
