Product Overview

The LTC4362IDCB-2#PBF is a monolithic overvoltage/overcurrent Protection Controller safeguards 2.5 to 5.5V systems from power supply overvoltage. It is designed for portable devices with multiple power supply options including wall adaptors, car battery adaptors and USB ports. The protector controls an internal 40mR N-channel MOSFET in series with the input power supply. During overvoltage transients, the protector turns off the MOSFET within 1µs, isolating downstream components from the input supply. In most applications, the protector rides through inductive cable transients without requiring transient voltage suppressors or other external components. An internal current sense resistor is used to implement overcurrent protection. It has a delayed start-up at plug-in and controlled dV/dt ramp-up for inrush current limiting. A PWRGD pin provides power good monitoring for VIN.
  • After an overcurrent fault, automatically restarts after a 130ms start-up delay
  • Internal 40mR N-channel MOSFET and 31mR RSENSE
  • Avalanche rated MOSFET requires no input capacitor or TVS for most applications
  • Controlled power-up dV/dt limits inrush current
  • Reverse voltage protection driver
  • Low current shutdown
