FIELD | TYPE | RESET | DESCRIPTION |
|---|---|---|---|---|
| 7 | EN_IBAT | R/W | 0b |
IBAT Enable Enable the IBAT output buffer. In low power mode (REG0x01[7] = 1), IBAT buffer is always disabled regardless of this bit value. 0b Turn off IBAT buffer to minimize Iq <default at POR> 1b: Turn on IBAT buffer |
| 6-5 | EN_PROCHOT
_LPWR |
R/W | 00b |
Enable PROCHOT during battery only low power mode With battery only, enable IDCHG or VSYS in PROCHOT with low power consumption. Do not enable this function with adapter present. Refer to PROCHOT During Low Power Mode for more details. 00b: Disable low power PROCHOT <default at POR> 01b: Enable IDCHG low power PROCHOT 10b: Enable VSYS low power PROCHOT 11b: Reserved |
| 4 | EN_PSYS | R/W | 0b |
PSYS Enable Enable PSYS sensing circuit and output buffer (whole PSYS circuit). In low power mode (REG0x01[7] = 1), PSYS sensing and buffer are always disabled regardless of this bit value. 0b: Turn off PSYS buffer to minimize Iq <default at POR> 1b: Turn on PSYS buffer |
| 3 | RSNS_RAC | R/W | 0b |
Input sense resistor RAC 0b: 10 mΩ <default at POR> 1b: 20 mΩ |
| 2 | RSNS_RSR | R/W | 0b |
Charge sense resistor RSR 0b: 10 mΩ <default at POR> 1b: 20 mΩ |
| 1 | PSYS_RATIO | R/W | 1b |
PSYS Gain Ratio of PSYS output current vs total input and battery power with 10-mΩ sense resistor. 0b: 0.25 µA/W 1b: 1 µA/W <default at POR> |
