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.
