TYPICAL APPLICATION
DESCRIPTION
Overvoltage Protection
Controller
TheLTC4360overvoltageprotectioncontrollersafeguards
2.5V 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, the LTC4360 turns off the MOSFET within 1s,
isolating downstream components from the input supply.
Inductive cable transients are absorbed by the MOSFET
and load capacitance. In most applications, the LTC4360
provides protection from transients up to 80V without
requiring transient voltage suppressors or other external
components.
TheLTC4360hasadelayedstart-upandanadjustabledV/dt
ramp-upforinrushcurrentlimiting.APWRGDpinprovides
power good monitoring for VIN. Following an overvolt-
age condition, the LTC4360 automatically restarts with a
start-up delay. The LTC4360-1 features a soft shutdown
controlled by the ON pin, while the LTC4360-2 controls an
optional external P-channel MOSFET for negative voltage
protection.
