DESCRIPTION

The MP5026 is a hot-swap protection device

designed to protect circuitry on its output from

transients on its input. It also protects its input

from undesired shorts and transients from its

output. The device can achieve up to 20A of

continuous output current (IOUT) per device at

room temperature.

The MP5026 limits the inrush current to the

load when a circuit card is inserted into a live

backplane power source. This limits the power

supply voltage drop. The MP5026 also limits

the

internal

MOSFET

current

(IFET)

by

controlling the gate voltage (VGATE) via a low-

power resistor connected between the ISET pin

and ground as well as soft-start ramp.

The MP5026 offers many features to simplify

system design, such as an integrated current

mirror that monitors IOUT and the integrated on-

die temperature sense. This eliminates the

need for an external current-sense power

resistor, power MOSFET, and temperature-

sense device.

The maximum load at the output is current-

limited via sense MOSFET topology. The

current limit is controlled by a low-power

resistor connected between ISET and ground.

The

MP5026

provides

a

variety

of

fault

protections, including over-current protection

(OCP), short-circuit protection (SCP), over-

temperature

protection

(OTP),

damaged

MOSFET

detection,

over-voltage

protection

(OVP), and under-voltage protection (UVP).

The

MP5026

is

available

in

an

LGA-26

(4mmx4mm) package.
