Load Protected from Reverse and Overvoltage at VIN

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.

Two comparator inputs allow configuration of the

overvoltage (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 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.
