LTC4367
100V Overvoltage,
Undervoltage and Reverse
Supply Protection Controller
DESCRIPTION
The
LTC
®
4367
protects applications where power sup-
ply input voltages may be too high, too low or even
negative. It does this by controlling the gate voltages of
a pair of external N-channel MOSFETs to ensure that the
output stays within a safe operating range.The LTC4367
withstands voltages between –40V and 100V and has an
operating range of 2.5V to 60V, while consuming only
70µA in normal operation.
Two comparator inputs allow configuration of the over-
voltage (OV) and undervoltage (UV) set points using an
external resistive divider. A shutdown pin provides external
control for enabling and disabling the MOSFETs as well
as placing the device in a low current shutdown state. A
fault output indicates that the GATE pin is pulling low when
the part is in shutdown or the input voltage is outside the
UV and OV set points.
The LTC4367 has a 32ms turn-on delay that debounces
live connections and blocks 50Hz to 60Hz AC power. For
fast recovery after faults, the LTC4367-1 has a reduced
turn-on delay of 500µs.
