LTC4367  
100V Overvoltage,  
Undervoltage and Reverse  
Supply Protection Controller  
DESCRIPTION  
FEATURES  
n
Wide Operating Voltage Range: 2.5V to 60V  
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.

Overvoltage Protection to 100V

LTC4367: 32ms Recovery from Fault  
n
LTC4367-1: Fast 500µs Recovery from Fault  
n
No Input Capacitor or TVS Required for Most  
Applications  
n
Adjustable Undervoltage and Overvoltage Thresholds  
Two comparator inputs allow configuration of the over-  
voltage (OV) and undervoltage (UV) set points using an  
externalresistivedivider.Ashutdownpinprovidesexternal  
control for enabling and disabling the MOSFETs as well  
as placing the device in a low current shutdown state. A  
faultoutputindicatesthattheGATEpinispullinglowwhen  
the part is in shutdown or the input voltage is outside the  
UV and OV set points.

APPLICATIONS  
n
Portable Instrumentation  
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.
