Bit 7..6 | VSYS1..VSYS0: |
00 = the output voltage of the power path at pin SYS tracks the battery voltage;
VSYS = VBAT + 200 mV (Vbat > 3.3 V); VSYS = 3.4 V (VBAT ≤ 3.3 V); V_DPPM = 1 is forced in this case 01 = the output voltage of the power path at pin SYS is regulated to 4.4 V 10 = the output voltage of the power path at pin SYS is regulated to 5 V 11 = the output voltage of the power path at pin SYS is regulated to 5.5 V |
|
Bit 5..4 | AC input current1.. AC input current0:
00 = 100 mA, input voltage DPPM enabled 01 = 500 mA, input voltage DPPM enabled 10 = 500 mA, input voltage DPPM disabled 11 = USB suspend mode; standby |
Bit 3 | TH_LOOP:
0 = the thermal loop is disabled 1 = the thermal loop is enabled and the charge current is reduced if the temperature exceeds 125°C |
Bit 2 | DYN_TMR (dynamic timer function):
0 = safety timers run with their normal clock speed 1 = clock speed for the safety timers is reduced based on the actual charge current if DPPM or thermal loop is active |
Bit 1 | TERM_EN (charge termination enable):
0 = charge termination will not occur and the charger will always be on 1 = charge termination enabled based on timers and termination current |
Bit 0 | CH_EN:
0 = the charger is disabled 1 = the charger is enabled |
