MP5921

16V, 50A, 1mΩ R_DS(ON)

Hot-Swap Intelli-Fuse Solution

DESCRIPTION

FEATURES

The MP5921 is a monolithic, integrated

controller and switch that contains a high-side

MOSFET and other circuitries that enable it to

work in standalone operation or to be controlled

by a hot-swap controller. The MP5921 drives up

to 50A of continuous current per device at room

temperature. With air flow, the continuous

current can reach 60A.

•

4V to 16V Operating Input Range

Maximum 50A Output Current

Supports 60A of Output Current with Air

Flow

Integrated Switch with 1mΩ R_DS(ON)

Built-In MOSFET Driver

3.0V LDO Output

Integrated Current Sensing with Sense

Output

•

The MP5921 limits the inrush current to the

load when a circuit card is inserted into a live

backplane power source, thereby limiting the

backplane’s voltage drop. The MP5921 limits

the internal MOSFET current by controlling the

gate voltage through the current limit reference

input and soft-start ramp.

•

Separate Current Sensing Output Used to

Program Over-Current Value

Built-In Insertion Delay

•

Adjustable Soft Start (SS)

Output Short-Circuit Protection (SCP)

Over-Temperature Protection (OTP)

Built-In Fuse Health Reporting

Fault Signal Output

The MP5921 offers many features to simplify

system design. It provides an integrated current

mirror to monitor the output current and on-die

temperature sensing, eliminating the need for

an external current-sense power resistor, power

MOSFET, and thermal sense device.

Parallel

Operation

for

High-Current

Applications

•

Integrated Intelli-Fuse Temperature Sense

Output Voltage Power-Down Control

Available in a FCQFN-28 (4mmx5mm)

Package

The MP5921 detects the power FET gate,

source, and drain short conditions and can

feedback to the hot-swap controller via the fault

reporting output (GOK). The MP5921 can be

paralleled for higher current applications. All

devices in parallel share current actively during

soft start.

APPLICATIONS

•

Hot Swap

PC Cards

Disk Drives

Servers

The MP5921 is available in a QFN-28

(4mmx5mm) package.
