The is an overvoltage 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 LTC4360 controls an external N-channel MOSFET in series with the input power supply. During overvoltage transients, it turns off the MOSFET within 1µs, isolating downstream components from the input supply. Inductive cable transients are absorbed by the MOSFET and load capacitance. In most applications, it provides protection from transients up to 80V without requiring transient voltage suppressors or other external components. It has a delayed start-up and an adjustable dV/dt ramp-up for inrush current limiting. A PWRGD pin provides power good monitoring for VIN. Following an overvoltage condition, the LTC4360 automatically restarts with a start-up delay. The LTC4360-1 features a soft shutdown controlled by the ON pin.
