Innovative PowerTM Active-Semi Proprietary―For Authorized Recipients and Customers REGISTER AND BIT DESCRIPTIONS CONT’D : Valid only when CHGIN UVLO Threshold<VCHGIN<CHGIN OVP Threshold. OUTPUT ADDRESS BIT NAME ACCESS DESCRIPTION REG6 0x61 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. REG7 0x64 [7:6] - R Reserved. REG7 0x64 [5:0] VSET R/W Output Voltage Selection. See the Output Voltage Programming section for more information. REG7 0x65 [7] ON R/W Regulator Enable Bit. Set bit to 1 to enable the regulator, clear bit to 0 to disable the regulator. REG7 0x65 [6] DIS R/W Output Discharge Control. When activated, LDO output is discharged to GA through 1.5kΩ resistor when in shutdown. Set bit to 1 to enable output voltage discharge in shutdown, clear bit to 0 to disable this function. REG7 0x65 [5] LOWIQ R/W LDO Low-IQ Mode Control. Set bit to 1 for low-power operating mode, clear bit to 0 for normal mode. REG7 0x65 [4:2] DELAY R/W Regulator Turn-On Delay Control. See the REG4, REG5, REG6, REG7 Turn-on Delay section for more information. REG7 0x65 [1] nFLTMSK R/W Regulator Fault Mask Control. Set bit to 1 enable fault- interrupts, clear bit to 0 to disable fault-interrupts. REG7 0x65 [0] OK R Regulator Power-OK Status. Value is 1 when output voltage exceeds the power-OK threshold, value is 0 otherwise. APCH 0x70 [7:0] - R/W Reserved. APCH 0x71 [7] SUSCHG R/W Charge Suspend Control Input. Set bit to 1 to suspend charging, clear bit to 0 to allow charging to resume. APCH 0x71 [6] - R/W Reserved. APCH 0x71 [5:4] TOTTIMO R/W Total Charge Time-out Selection. See the Charge Safety Timers section for more information. APCH 0x71 [3:2] PRETIMO R/W Precondition Charge Time-out Selection. See the Charge Safety Timers section for more information. APCH 0x71 [1:0] OVPSET R/W Input Over-Voltage Protection Threshold Selection. See the Input Over-Voltage Protection section for more information. APCH 0x78 [7] TIMRSTAT1 R/W Charge Time-out Interrupt Status. Set this bit with TIMRPRE[ ] and/or TIMRTOT[ ] to 1 to generate an interrupt when charge safety timers expire, read this bit to get charge time-out interrupt status. See the Charge Safety Timers section for more information. APCH 0x78 [6] TEMPSTAT1 R/W Battery Temperature Interrupt Status. Set this bit with TEMPIN[ ] and/or TEMPOUT[ ] to 1 to generate an interrupt when a battery temperature event occurs, read this bit to get the battery temperature interrupt status. See the Battery Temperature Monitoring section for more information. APCH 0x78 [5] INSTAT R/W Input Voltage Interrupt Status. Set this bit with INCON[ ] and/or INDIS[ ] to generate an interrupt when UVLO or OVP condition occurs, read this bit to get the input voltage interrupt status. See the Charge Current Programming section for more information. APCH 0x78 [4] CHGSTAT1 R/W Charge State Interrupt Status. Set this bit with CHGEOCIN[ ] and/or CHGEOCOUT[ ] to 1 to generate an interrupt when the state machine gets in or out of EOC state, read this bit to get the charger state interrupt status. See the State Machine Interrupts section for more information. APCH 0x78 [3] TIMRDAT1 R Charge Timer Status. Value is 1 when precondition time-out or total charge time-out occurs. Value is 0 in other case. |
