ChargeOption1 Register (I2C address = 31h) Field Descriptions BIT FIELD TYPE RESET DESCRIPTION 7 EN_IBAT R/W 0b IBAT Enable Enable the IBAT output buffer. In low power mode (EN_LWPWR=1b), 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 EN_PROCHOT_LPWR R/W 0b Enable PROCHOT during battery only low power mode With battery only, enable VSYS in PROCHOT with low power consumption. Do not enable this function with adapter present. Refer to Section 8.3.20.1 for more details. 0b: Disable Independent Comparator low power PROCHOT <default at POR> 1b: Enable Independent Comparator low power PROCHOT 5-4 PSYS_CONFIG R/W 11b PSYS Enable and Definition Register Enable PSYS sensing circuit and output buffer (whole PSYS circuit). In low power mode (EN_LWPWR=1b), PSYS sensing and buffer are always disabled regardless of this bit value. 00b: PSYS=PBUS+PBAT 01b: PSYS=PBUS 10b: Reserved 11b: Turn off PSYS buffer to minimize Iq<default at POR> 3 RSNS_RAC R/W 1b Input sense resistor RAC 0b: 10 mΩ 1b: 5 mΩ <default at POR> 2 RSNS_RSR R/W 1b Charge sense resistor RSR 0b: 10 mΩ 1b: 5 mΩ <default at POR> 1 PSYS_RATIO R/W 1b PSYS Gain Ratio of PSYS output current vs total system power 0b: 0.25 µA/W 1b: 1 µA/W <default at POR> 0 RESERVED R/W 1b RESERVED www.ti.com BQ25730 SLUSE65A – FEBRUARY 2021 – REVISED JANUARY 2024 Copyright © 2024 Texas Instruments Incorporated Submit Document Feedback 63 Product Folder Links: BQ25730 |
