LTC4362IDCB-1#TRPBF

Power Management - Specialized Overview

The LTC4362IDCB-1#TRPBF is a monolithic overvoltage and overcurrent protector manufactured by Analog Devices Inc. It safeguards 2.5V to 5.5V systems from power supply overvoltage transients. The device controls an internal N-channel MOSFET with a typical on-resistance of 40mΩ in series with the input power supply. During overvoltage events, it turns off the MOSFET within 1μs to isolate downstream components. An internal current sense resistor implements overcurrent protection. The component operates within a specified temperature range and utilizes a DFN-8 surface-mount package.
