Manufacturer: Analog Devices

Overview: LTC4365.

General Description

n Wide Operating Voltage Range: 2.5V to 34V n Overvoltage Protection to 60V n Reverse Supply Protection to –40V n LTC4365: Blocks 50Hz and 60Hz AC Power n LTC4365-1: Fast (1ms) Recovery from Fault n No Input Capacitor or TVS Required for Most Applications n Adjustable Undervoltage and Overvoltage Protection Range n Charge Pump Enhances External N-Channel MOSFET n Low Operating Current: 125µA n Low Shutdown Current: 10µA n Compact 8-Lead, 3mm × 2mm DFN and TSOT-23 (ThinSOT™) Packages nn AEC-Q100 Qualified for Automotive Applications APPLICATIONS n Portable Instrumentation n Industrial Automation n Laptops n Automotive Surge Protection 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.
