Name
Charger regulator voltage setting
Charger regulator current setting
Internal trickle charger enabling
Battery thermistor check disable
SPI control over BATTFET pin (M3)
FETOVRD: 0 = BATTFET output are controlled by hardware
FETOCTRL: 0 = BATTFET is driven high if FETOVRD is set
Reverse mode enabling
0 = Reverse mode disabled
1 = Reverse mode enabled
Power limiter setting and disabling
PLIMDIS: 0 = Power limiter enabled
Charge LED indicator enabling
0 = CHRGLED disabled
1 = CHRGLED enabled
Charger state machine restart
Selects between standalone or software controlled charging operation
0 = Standalone charging
1 = Software controlled charging
Allows for SPI control over-voltage and current settings in standalone charging mode
Controls charging resume behavior
0 = Enables cycling
1 = Disables cycling
Charger attach
CHRGRAW over-voltage, excessive power dissipation, timeout, battery out of temperature range
Charger fault mode sense bits
Charger enable sense bit
USB over-voltage
Short-circuit detection in reverse mode
Charger path reverse current, detection based on CHGCURR threshold
Charge current threshold, detection based on CHGCURR threshold
Charger path regulation mode, detection based on BATTCYCL threshold
Wall Charger Detect
CHRSE1B pin sense
Charger configuration sense, serial versus single. A logic 1 indicates a serial path.
CHRGISNS-BPSNS at 35 mA flowing into phone, used for end of charge detection, charger removal and
charge current reversal
BATT at 3.0 V, used to increase charge current (40/80 mA and 80/560 mA), detect a dead battery insertion
while charging
BP at 3.2 V, used to allow turn on when charging from USB, closes M3 when in serial path
BATT at 3.4 V, used to allow turn on when charging from USB, closes M3 when in serial path
BPSNS at 98% of charger voltage setting, used to restart charging, used by CCCVI
1 = Power limiter disabled
1 = BATTFET controlled by the state of the FETCTRL bit
1 = BATTFET is driven low if FETOVRD is set
