Overvoltage/Overcurrent
Protection Controller
DESCRIPTION
The LTC®4361 overvoltage/overcurrent protection con-
troller safeguards 2.5V to 5.5V systems from input sup-
ply overvoltage. It is designed for portable devices with
multiple power supply options including wall adaptors,
car battery adaptors and USB ports.
The LTC4361 controls an external N-channel MOSFET
in series with the input power supply. During overvolt-
age transients, the LTC4361 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
LTC4361 provides protection from transients up to 80V
without requiring transient voltage suppressors or other
external components.
The LTC4361 has a delayed start-up and adjustable dV/
dt ramp-up for inrush current limiting. A PWRGD pin
provides power good monitoring for VIN. The LTC4361
features a soft shutdown controlled by the ON pin and
drives an optional external P-channel MOSFET for nega-
tive voltage protection. Following an overvoltage condi-
tion, the LTC4361 automatically restarts with a start-up
delay. After an overcurrent fault, the LTC4361-1 remains
off while the LTC4361-2 automatically restarts after a
130ms start-up delay.
