Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7–6 | TIMER[1:0] | R/W | 10b |
Charge safety timer setting (fast-charge timer) 00b = 4h 01b = 5h 10b = 6h 11b = 8h |
5 | TMR_EN | R/W | 1b |
Safety timer enable 0b = Precharge timer and fast charge timer are disabled. 1b = Precharge timer and fast charge time are enabled. |
4 | NTC_TYPE | R/W, E2 | 1b |
NTC type (for battery temperature measurement) 0b = 100k (curve 1, B = 3960) 1b = 10k (curve 2, B = 3480) |
3 | RESET | R/W | 0b |
Charger reset 0b = Inactive 1b = Reset active. This bit must be set and then reset via the serial interface to restart the charge algorithm. |
2 | TERM | R/W | 0b |
Charge termination on-off 0b = Charge termination enabled, based on timers and termination current 1b = Current-based charge termination does not occur and the charger is always on |
1 | SUSP | R/W | 0b |
Suspend charge 0b = Safety timer and precharge timers are not suspended. 1b = Safety timer and precharge timers are suspended. |
0 | CHG_EN | R/W, E2 | 1b |
Charger enable 0b = Charger is disabled. 1b = Charger is enabled. |
