DEFAULT Mode

DEFAULT mode is used when I

C communication is not available. DEFAULT mode is entered in the following

situations:

1. When the charger is enabled and V

BAT

< V

BATGD

before I

C communication is established

2. When the watchdog timer expires without a reset from the I

C interface and the safety timer has not expired.

3. When the device comes out of any fault condition (sleep mode, OVP, faulty adapter mode, etc.) before I

communication is established

In DEFAULT mode, the I

C registers are reset to the default values. The 27-minute safety timer (no timer for

bq24168) is reset and starts when DEFAULT mode is entered. The default value for VBATREG is 3.6V, and the

default value for I

CHARGE

is 1A. The input current limit for the IN input is set to 1.5A. The input current limit for the

USB input is determined by the D+/D– detection (bq24160/3) or PSEL (bq24161/1B/8). PSEL and D+/D–

detection have no effect on the IN input. Default mode is exited by programming the I

C interface. Once I

communication is established, PSEL has no effect on the USB input. Note that if termination is enabled and

charging has terminated, a new charge cycle is NOT initiated when entering DEFAULT mode.
