If you need dual input, then I suggest either the bq24160A or bq24168 which have both the watchdog and safety timers disabled. After the first I2C write to the registers, the registers retain those values until an event like battery removal or overvoltage…
The bq24160 requires the HOST to send the watchdog signal or the IC will return to default mode settings. The EVM GUI provides that function. If the customer does want the watchdog in the final application, they will need to change to the bq24168.
1. Until both the input voltage and battery voltage is removed. Note that certain events, like watchdog timer expiring, cause multiple registers to automatically change.
2. You would have to select an IC option that has the watchdog timer disabled, like…
