DEMO MANUAL DC1575A

LTC4362-2:

Monolithic Overvoltage/

Overcurrent Protector

DESCRIPTION

Demonstration circuit DC1575A features the LTC

4362,

a monolithic overvoltage/overcurrent protector that 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 LTC4362 controls an internal 40mΩ N-channel MOSFET

in series with the input power supply. During overvoltage

transients, the LTC4362 turns off the MOSFET within 1μs,

isolating downstream components from the input supply.

In most applications, the LTC4362 rides through induc-

tive cable transients without requiring transient voltage

suppressors or other external components. An internal

current sense resistor is used to implement overcurrent

protection.

The LTC4362 has a delayed start-up at plug-in and con-

trolled dV/dt ramp-up for inrush current limiting. A PWRGD

pin provides power good monitoring for V

. The LTC4362

features a soft-shutdown controlled by the ON pin and

drives an optional external P-channel MOSFET for negative

voltage protection. Following an overvoltage condition,

the LTC4362 automatically restarts with a 130ms delay.

After an overcurrent fault, the LTC4362-1 remains off while

the LTC4362-2 (featured on the DC1575A) automatically

restarts after a 130ms delay.

DC1575A demonstrates two protection schemes selected

with a jumper. The ﬁrst selection is overvoltage and

overcurrent protection. The second selection is overvolt-

age, overcurrent, and negative voltage protection. Also

on the DC1575A is ON control with another jumper, input

LEDs indicating positive or negative input voltage, output

LED and connection for USB protected output.
