LTC4356 Datasheet PDF - Linear Technology

DESCRIPTION
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.

FEATURES
■ Wide Operating Voltage Range: 2.5V to 34V
■ Overvoltage Protection to 60V
■ Reverse Supply Protection to –40V
■ Blocks 50Hz and 60Hz AC Power
■ No Input Capacitor or TVS Required for Most Applications
■ Adjustable Undervoltage and Overvoltage Protection Range
■ Charge Pump Enhances External N-Channel MOSFET
■ Low Operating Current: 125μA
