EEPROM programmable second address bit.
When this bit is set, the trim registers including this register are not writable via SMBus. To
make registers writable again, the trim-lock bit in the EEPROM must first be erased and the
value downloaded using either power-up or test download.

Current Limit Disable
R/W
Mask effect of OCP to general logic (status flag still gets asserted) when curr_lim_dis = 1.
6
PEN Polarity
R/W
Sets polarity of PEN output.
5
CBD Polarity
R/W
Sets polarity of CBD output.

R/W
Don’t Care.
2
OCP Ridethrough
R/W
Set this bit to 1 when OCP ridethrough is required. A small delay still exists. Refer to Reg 12h.
1
GND_OK Disable
R/W
Disable GROUND_OK input to power management debounce logic.
0
CBD Latch Mode
R/W
Select CBD latch mode. 0 = nonlatching; 1 = latching.

R/W
Description
7
Restart Mode
R/W
Restart mode (rsm). When rsm = 1, the circuit attempts to restart the supply after an
undervoltage or overcurrent at about 1-second intervals.
Latch mode. When rsm = 0, UV and OC faults latch the output off. Cycling PSON or removing
the supply to the IC is then required to reset the latch and permit a restart.
6
Micro AC OK
R/W
Configure microprocessor to control/gate signal from AC_IN_OK to AC_S_OK. See Table 43.
0 = Standalone.
1 = Microprocessor support mode.
5
Micro AC SENSE
R/W
Microproccessor control of AC
