12V, 7mΩ R_DSonHot-Swap Protection

Device with Current Monitoring

The Future of Analog IC Technology

FEATURES

DESCRIPTION

•

Integrated 7mꢀ Power FET

The MP5021 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 coming

from its output.

Adjustable Current Limit (5A to 15A)

Output Current Measurement

±5% Current Limit and Monitor Accuracy

Fast Response (<200ns) for Short Protection

PG Detector and FLTB Indication

PG Assert Low at VIN=0

Damaged MOSFET Detection

External Soft-Start

Programmable EN Blanking Time

Under/Over-Voltage Lockout

Thermal Protection

At start up, the slew rate at the output limits the

in-rush current. An external capacitor at the SS

pin controls the slew rate.

The maximum output load is current limited using

a sense FET topology whereby a low-power

resistor from the ISET pin to ground controls the

magnitude of the current limit.

Small 3mm×5mm QFN Package

An internal charge pump drives the gate of the

power device, allowing for a power FET with a

very low ON resistance of 7mΩ.

APPLICATIONS

•

Hot Swappable:

o PC Cards

o Disk Drives

o Laptops

The MP5021 includes an IMON option to

produce a voltage proportional to the current

through the power device, as set by a resistor

from the IMON pin to ground.

All MPS parts are lead-free and adhere to the RoHS directive. For MPS green

status, please visit MPS website under Products, Quality Assurance page.

The MP5021 includes an optional discharge

function that provides a discharge path for the

external output capacitor when the part is

disabled. Fault protections include current-limit

protection, thermal shutdown, and damaged-

MOSFET detection. Both the current limit and

thermal shutdown have user-settable auto-retry

and latch-off mode. The device also features

over-voltage protection and under-voltage

protection
