LDO2 Enable Configuration (Read only)
000 = Disabled
001 = Enabled always when BAT/SYS is present
010 = Enabled
at 0% of Boot/POR Process Delay Control
011 = Enabled
at 25% of Boot/POR Process Delay Control
100 = Enabled
at 50% of Boot/POR Process Delay Control
101 = Disabled
110 = Disabled
111 = Controlled by LDO2En[1:0] after 100% of Boot/POR Process Delay Control
LDO2ActDSC
LDO2 Active Discharge Control
0 = LDO2 output will be actively discharged only in HardReset mode
1
= LDO2 output will be actively discharged in HardReset mode and also when its Enable goes Low. The active
discharge circuit will continue to draw additional quiescent current as long at this bit is set to 1, even when the
LDO is disabled. (See
Electrical Characteristics
table.)
LDO2En[1:0]
LDO2 Enable Configuration (effective only when LDO2Seq = 111)
00 = Disabled – LDO’s OUT not actively discharged unless HardReset/ShutDown/Off
Mode
01 = Enabled
10 = Enabled when MPC0 is high (regardless of MPC1)
11 = Enabled when MPC1 is high (regardless of MPC0)
LDO2Mode
LDO2 Mode Control
0 = Normal LDO operating mode
1
= Load switch mode. FET is either fully ON or OFF depending on state of LDO2En. When FET is ON, the
output is unregulated. This setting is internally latched and can change only when the LDO is disabled.
