| BIT | FIELD | TYPE | RESET | DESCRIPTION |
|---|---|---|---|---|
| 7 | STAT_AC | R | 0b | Input source status. STAT_AC is valid as long as VBUS go within 3.5-V to 26-V range. It is different from CHRG_OK bit, When CHRG_OK is valid, STAT_AC must be valid, but if STAT_AC is valid, it is not necessary CHRG_OK is valid. There are Force converter off, ACOC, TSHUT , SYSOVP, VSYS_UVP, BATOVP can pull low CHRG_OK. 0b: Input not present 1b: Input is present |
| 6 | ICO_DONE | R | 0b | After the ICO routine is successfully executed, the bit goes 1. 0b: ICO is not complete 1b: ICO is complete |
| 5 | IN_VAP | R | 0b | 0b: Charger is not operated in VAP mode 1b: Charger is operated in VAP mode Digital status bit indicates VAP has enabled(1) or disabled(0). The enable of VAP mode only follows the host command, which is not blocked by any status of /PROCHOT. The exit of VAP mode also follows the host command, except that any faults will exit VAP mode automatically. STAT_EXIT_VAP (REG0x22[8]) becomes 1 which will pull low /PROCHOT until host clear. The host can enable VAP by setting OTG/VAP/FRS pin high and 0x32[5]=0, disable VAP by setting either OTG/VAP/FRS pin low or 0x32[5]=1. Any faults in VAP When IN_VAP bit goes 0->1, charger should disable VINDPM, IIN_DPM, ICRIT, ILIM pin, disable PP_ACOK if it is enabled, enable PP_VSYS if it is disabled. When IN_VAP bit goes 1->0, charger should enable VINDPM, IIN_DPM, ICRIT, ILIM pin function. |
| 4 | IN_VINDPM | R | 0b | 0b: Charger is not in VINDPM during forward mode, or voltage regulation during OTG mode 1b: Charger is in VINDPM during forward mode, or voltage regulation during OTG mode |
| 3 | IN_IIN_DPM | R | 0b | 0b: Charger is not in IIN_DPM during forward mode. 1b: Charger is in IIN_DPM during forward mode. |
| 2 | IN_FCHRG | R | 0b | 0b: Charger is not in fast charge 1b: Charger is in fast charger |
| 1 | IN_PCHRG | R | 0b |
0b: Charger is not in pre-charge 1b: Charger is in pre-charge |
| 0 | IN_OTG | R | 0b | 0b: Charger is not in OTG 1b: Charge is in OTG |
| BIT | FIELD | TYPE | RESET | DESCRIPTION |
|---|---|---|---|---|
| 7 | Fault ACOV | R | 0b | The status are latched if triggered until a read from host. 0b: No fault 1b: ACOV |
| 6 | Fault BATOC | R | 0b | The status is latched if triggered until a read from host. Fault indicator for BATOC only during normal operation. However, in PTM mode when EN_BATOC=1b, this status bit is fault indicator for both BATOVP and BATOC; when EN_BATOC=0b, this status bit is not effective. 0b: No fault 1b: BATOC is triggered |
| 5 | Fault ACOC | R | 0b | The status is latched if triggered until a read from host. 0b: No fault 1b: ACOC |
| 4 | Fault SYSOVP | R/W | 0b | SYSOVP Status and Clear. SYSOVP fault is latched until a clear from host by writing this bit to 0. When the SYSOVP occurs, this bit is HIGH. During the SYSOVP, the converter is disabled. After the SYSOVP is removed, the user must write a 0 to this bit or unplug the adapter to clear the SYSOVP condition to enable the converter again. 0b: Not in SYSOVP <default at POR> 1b: In SYSOVP. When SYSOVP is removed, write 0 to clear the SYSOVP latch. |
| 3 | Fault VSYS_UVP | R/W | 0b | VSYS_UVP fault status and clear. VSYS_UVP fault is latched until a clear from host by writing this bit to 0. 0b: No fault <default at POR> 1b: When system voltage is lower than VSYS_UVP, then 7 times restart tries are failed. |
| 2 | Fault Force_Converter_Off | R | 0b | The status is latched if triggered until a read from host. 0b: No fault 1b: Force converter off triggered (when FORCE_CONV_OFF (REG0x30[3])=1b) |
| 1 | Fault_OTG_OVP | R | 0b | The status is latched if triggered until a read from host. 0b: No fault 1b: OTG OVP fault is triggered |
| 0 | Fault_OTG_UVP | R | 0b | The status is latched if triggered until a read from host. 0b: No fault 1b: OTG UVP fault is triggered |
