Overview
PDSG_EN: This bit enables the bq78350-R2 device to use the GPIO_B pin during PRE-DISCHARGE
mode.
0 = The bq78350-R2 device does not use GPIO_B for PRE-DISCHARGE mode (default)
1 = The bq78350-R2 device controls GPIO_B under normal charge control algorithm.
KEY_POL: This bit configures the KEYIN input detection polarity.
0 = KEYIN detection is active low (default).
1 = KEYIN detection is active high.
PCHG_POL: Configures the bq78350-R2 device PRECHG pin output polarity. If PCHG_EN = 0, then
this bit has no influence.
0 = The bq78350-R2 device configures the PRECHG as active low (default).
1 = The bq78350-R2 device configures the PRECHG as active high, requiring an external pull
up.
SLEEPCHG: CHG FET is enabled during SLEEP.
0 = CHG FET is off during SLEEP (default).
1 = CHG FET remains on during SLEEP.
CHGFET: FET action on valid charge termination
0 = FET active
1 = Charging and precharging disabled, FET off (default)
CHGIN: FET action in CHARGE INHIBIT mode
0 = FET active (default)
1 = Charging and precharging disabled, FETs off
CHGSU: FET action in CHARGE SUSPEND mode
0 = FET active (default)
1 = Charging and precharging disabled, FETs off
OTFET: FET action in OVERTEMPERATURE mode
0 = No FET action for overtemperature condition (default)
1 = CHG and DSG FETs will be turned off for overtemperature conditions.
KEY_EN: Enables the bq78350-R2 device to use the KEYIN pin function.
0 = The bq78350-R2 device never uses KEYIN (default).
1 = The bq78350-R2 device KEYIN is used to control the DSG FET.
PCHG_EN: This bit enables the bq78350-R2 device to use the PRECHG pin during PRECHARGE
mode.
0 = The bq78350-R2 device never uses PRECHG.
1 = The bq78350-R2 device controls PRECHG under normal charge control algorithm (default).
The Pre-Discharge:[FET ON Time] setting is included in the following data flash:
Class Subclass Name Type Min Max Default Unit
Power Pre-Discharge FET ON Time U2 0 65535 10 s
3.1.2 Command Changes for PRE-DISCHARGE Mode
3.1.2.1 ManufacturerAccess() 0x0057 ManufacturingStatus
This command returns the ManufacturingStatus() flags on ManufacturerBlockAccess() or
ManufacturerData(). A new [PDSG_TEST] bit was added here for the bq78350-R2 device.
