DESCRIPTION

The MP5022C is a hot-swap protection device

designed to protect circuitry on its output from

transients on its input. The MP5022C also

protects its input from unwanted shorts and

transients coming from its output.

During start-up, inrush current is limited by the

slew rate at the output. The slew rate is

controlled by an external capacitor at SS.

The maximum load at the output is current-

limited

through

sense

FET

topology.

The

magnitude of the current limit is controlled by a

low-power resistor from ISET to ground.

An internal charge pump drives the gate of the

power device, allowing a power FET with a very

low on resistance of 3

mΩ to turn on.

The MP5022C includes an IMON option that

produces a voltage proportional to the current

through the power device set by a resistor from

IMON to ground.

Full protection features includes current limit,

thermal shutdown, damaged MOSFET detection,

over-voltage protection (OVP), and under-voltage

protection (UVP).

The

MP5022C

is

available

in

a

QFN-22

(3mmx5mm) package.
