| BIT | BIT NAME | DESCRIPTION |
|---|---|---|
| [15:14] | Battery Depletion Threshold (BAT_DEPL_VTH) | Battery over-discharge threshold. During LEARN cycle, when battery voltage is below the depletion threshold, the IC exits LEARN mode. During boost mode, when battery voltage is below the depletion threshold, the IC exits boost mode. 00: Falling threshold = 60% of ChargeVoltage() register setting 01: Falling threshold = 64% of ChargeVoltage() register setting 10: Falling threshold = 68% of ChargeVoltage() register setting 11: Falling threshold = 72% of ChargeVoltage() register setting (default at POR) |
| [13:12] | RAC and RSR Ratio (RSNS_RATIO) | Adjust the PMON calculation for different input sense resistor RAC and charge sense resistor RSR ratio. Reference Table 6-1 for further detail.. 00: RAC and RSR 1:1 (default at POR) 01: RAC and RSR 2:1 10: RAC and RSR 1:2 11: Reserved |
| [11] | IDCHG Buffer Enable (EN_IDCHG) | IDCHG pin output enable. 0: Disable IDCHG output to minimize Iq (default at POR) 1: Enable IDCHG output |
| [10] | PMON Buffer Enable (EN_PMON) | PMON pin output enable. 0: Disable PMON output to minimize Iq (default at POR) 1: Enable PMON output |
| [9] | PMON Gain (PMON_RATIO) | Ratio of PMON output current vs total input and battery power. Reference Table 6-1 for further detail. 0: 0.25 μA/W for 10 mΩ sense resistors 1: 1 μA/W for 10 mΩ sense resistors (default at POR) |
| [8] | Reserved | 0 - Reserved |
| [7] | Independent Comparator Reference (CMP_REF) | Independent comparator internal reference. 0: 2.3 V (default at POR) 1: 1.2 V |
| [6] | Independent Comparator Polarity (CMP_POL) | Independent comparator output polarity. With comparator polarity bit set as 1, the hysteresis is set by placing a resistor from CMPIN to CMPOUT. With comparator polarity bit set as 0, the hysteresis is internally set as 100mV. 0: When CMPIN is above internal threshold, CMPOUT is LOW (default at POR) 1: When CMPIN is above internal threshold, CMPOUT is HIGH |
| [5:4] | Independent Comparator Deglitch Time (CMP_DEG) | Independent comparator deglitch time, applied on the edge where CMPOUT goes LOW. No deglitch time is applied on the rising edge of CMPOUT. If the value in REG0x3B[7:3] is changed by host, deglitch time will get reset. 00: Independent comparator is disabled 01: Independent comparator is enabled with output deglitch time 1 μs Note: 1 μs deglitch should not be used when low-power mode bit is enabled. 10: Independent comparator is enabled with output deglitch time 2 ms (default at POR) 11: Independent comparator is enabled with output deglitch time 5 sec |
| [3] | Power Path Latch-off Enable (EN_FET_LATCHOFF ) | When independent comparator is triggered, both ACFET/RBFET turn off. The latch off is cleared by either POR or write this bit to zero. This function is available with CMP_DEG setting of 2 ms (10) or 5 sec (11). 0: When independent comparator is triggered, no power path latch off (default at POR) 1: When independent comparator is triggered, power path latches off. |
| [2] | MORE_TURBO_PRESET | Add more preset for turbo boost mode entry which could help reduce IIN overshoot but at same
time slightly increase IIN undershoot and IBAT discharge overshoot as trade off: 0: Disable 1: Enable (default at POR) |
| [1] | Discharge SRN for Shipping Mode (EN_SHIP_DCHG) | Discharge SRN pin for 200 ms with minimum 5-mA current. 0: Disable discharge mode (default at POR) 1: Enable discharge mode |
| [0] | EN_DYNAMIC_CHARGE_OCP | Enable short time(80ys) CHG_OCP threshold lift when ramp up charge current after exiting
turbo, this is used to avoid ICHG chatter at beginning part of ICHG recover: 0: Disable (default at POR) 1: Enable |
