Figure 1. Functional Diagram
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.
