For all line, static load and

During a short-circuit or when

current limit of 12 V is exceeded,

12 V latches off, 3.3 V remains

on. The 12 V can only be

enabled by cycling power, or

via the I2C interface, providing

the fault condition has cleared.

Short circuit of less than 10 mΩ

Output self recovers upon

removal of the short circuit

If the 3.3 V goes outside these

limits, the 12 V output is

disabled. The 12 V output is

enabled again by cycling input

power, or by resetting via I2C
