LTC4365

Overvoltage,

Undervoltage and Reverse

Supply Protection Controller

DESCRIPTION

FEATURES

The LTC^®4365 protects applications where power supply

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 LTC4365 can

withstand voltages between –40V and 60V and has an

operating range of 2.5V to 34V, while consuming only

125µA in normal operation.

Wide Operating Voltage Range: 2.5V to 34V

Overvoltage Protection to 60V

Reverse Supply Protection to –40V

LTC4365: Blocks 50Hz and 60Hz AC Power

LTC4365-1: Fast (1ms) Recovery from Fault

No Input Capacitor or TVS Required for Most

Applications

Adjustable Undervoltage and Overvoltage

Protection Range

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

fault output provides status of the gate pin pulling low. A

fault is indicated when the part is in shutdown or the input

voltage is outside the UV and OV set points.

Charge Pump Enhances External N-Channel MOSFET

Low Operating Current: 125µA

Low Shutdown Current: 10µA

Compact 8-Lead, 3mm × 2mm DFN and

TSOT-23 (ThinSOT™) Packages

AEC-Q100 Qualified for Automotive Applications

APPLICATIONS

The LTC4365 has a 36ms turn-on delay that debounces

live connections and blocks 50Hz to 60Hz AC power. For

fast recovery after faults, the LTC4365-1 has a reduced

1ms turn-on delay.
