trim_lock
R/W
R/W
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.

Description
Mask effect of OCP to general logic (status flag still gets asserted) when curr_lim_dis = 1.
Sets polarity of PEN output. Refer to the Configuration table (Table 45).
Don’t Care.
Set this bit to 1 when 0 OCP ridethrough is required. A small delay still exists. Refer to Reg 12h

rsm
R/W
R/W
Description
Restart Mode. 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.
