FAULT_
goes low when any of the following conditions
occur:
The input voltage is below the undervoltage-lockout
(UVLO) threshold.
The switch junction temperature exceeds the thermal
shutdown temperature limit of +160
°
C.
The switch is in current limit or short-circuit limit
mode and the fault-blanking period is exceeded.
The fault indicators have a latching delay to prevent
short
FAULT_
pulses. After the fault-condition is
removed, the
FAULT_
output will deassert after a 20ms
delay. Ensure that the MAX1812 has adequate input
bypass capacitance to prevent glitches from triggering
FAULT_
outputs. Input glitches greater than 0.2V/μS
may cause spurious
FAULT_
transitions.
