DB_EXIT
Read/Write

0
DESCRIPTION
Exit Dead-Battery Charge Mode. If DBCHG = 1, setting
DB_EXIT to 1 stops the 45-minute timer, sets DBCHG to 0,
and leaves CHG_EN = 1. DB_EXIT is automatically reset to
0 if V_BAT reaches the dead-battery threshold.
0 = Do not exit dead-battery mode
1 = Exit dead-battery mode
DB_IDLE
Read/Write
5
Dead-Battery Idle Mode. DB_IDLE = 1 in dead-battery
mode to forces the USB switch to close. DB_IDLE is
0
automatically reset when the USB switch is closed.
0 = Dead-battery mode off or test completed
1 = Dead-battery mode on or test still needed
Suspend Mode Selection
SUS_LOW

0 (1)*
0 = When the charger is disabled, CE1 = CE2 = 1
1 = When the charger is disabled, CE1 = CE2 = 0

CE Outputs Force Enable
0 = CE outputs follow the charger-detection finite state
0
machine (FSM)
1 = CE outputs follow the CE[2:0] register regardless of the
result from the charger-detection FSM

CE Outputs (CE2, CE1, CE0). If CE_FRC = 0, registers are
set by the result of charger FSM. If CE_FRC = 1, registers
are set by I²C command only.
Reserved
0 = Normal detection
1 = Resistive detection
USB Compliance
0 = Device is not USB compliant
1 = Device is USB compliant
LOUT Enable
0 = LOUT off
1 = LOUT on as per SFOUTASRT
SFOUTASRT
Read/Write

LOUT Assert Timing
1
0 = LOUT asserts when the charger-detection FSM
completes
1 = LOUT asserts after valid V_BUS voltage detection
DCD_EXIT
Read/Write
0
Exit Charger-Type-Detection Routine After DCD_T is Set to 1
1
0 = Disabled
1 = Enabled
Note: CP_ENA, DCHK, USB_CHGDET, DCD_EN, SUS_LOW, CE_FRC, CE, USB_CPL, SFOUT_EN, SFOUTASRT, and DCD_EXIT
can be configured to have different default values. Contact the factory for more information.
*Default value for MAX14578AE only.
