DESCRIPTION
The
LTC
®
4360
overvoltage protection controller safe-
guards 2.5V to 5.5V systems from power supply over-
voltage. 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 1µs,
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.
The LTC4360 has a delayed start-up and an adjustable
dV/dt ramp-up for inrush current limiting. A
PWRGD
pin
provides power good monitoring for V
IN
. Following an
overvoltage condition, the LTC4360 automatically restarts
with a start-up delay. The LTC4360-1 features a soft shut-
down controlled by the
ON
pin, while the LTC4360-2 con-
trols an optional external P-channel MOSFET for negative
voltage protection.
