DESCRIPTION
The
LTC
®
4368
protects applications from power supply
voltages that may be too high, too low, or even negative
and from overcurrent faults in both forward and reverse
directions. The LTC4368 controls the gate voltage of a pair
of external N-channel MOSFETs to ensure that the load
is connected to the input supply only when there are no
voltage or current faults.
Two comparator inputs allow configuration of the over-
voltage (OV) and undervoltage (UV) set points using an
external resistive divider. A current sense resistor sets the
forward and reverse circuit breaker current thresholds.
After a forward current fault, the LTC4368 will either latch-
off power, or retry after a user adjustable delay. After a
reverse current fault, the LTC4368 waits for the output to
fall 100mV below the input to reconnect power to the load.
The LTC4368 has a 32ms turn-on delay that debounces
live supply input connections and blocks 50Hz and 60Hz
AC power. UV/OV faults also trigger the 32ms recovery
delay before the external MOSFETs are turned back on.
