MP5018

5V, 1A-5A Current Limit Switch

with Reverse Current Blocking

and Output Over-voltage Clamp

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP5018 is a protection device designed to

protect circuitry on the output from transients on

input (V_CC). It also protects V_CCfrom undesired

shorts and transients coming from the output.

•

SAS Disable to support DEVSLP or

POWER_DOWN

4.5V to 5.5V Continued Operating Input

Range

•

16V Absolute Maximum Input Voltage

5.8V Fast OVP Response

Reverse Current Blocking

Integrated 45mΩ Power FET

Adjustable Current-Limit or Fixed Current

Limit when floating ILIMIT pin

210μA Typical Low Quiescent Current

Adjustable Soft Start time

At startup, inrush current is limited by the slew

rate at the output. The slew rate is controlled by

a small capacitor at the SS pin. Floating the SS

pin provides 13ms soft-start time.

The maximum load at the output is current

limited. The magnitude of the current limit is

controlled by an external resistor from ILIMIT to

GND. Floating ILIMIT pin provides 3A fixed

current limit. By controlling the gate voltage of a

pair of N-channel MOSFETs, any current

flowing from output to input is blocked.

•

Fault Indication

Latch-off Thermal Protection

Available in QFN12(2mmx3mm) Package

ESD Compliant to 2kV HBM and 1kV

CDM

Under Voltage Lockout (UVLO) assures that

input is above the minimum operating threshold,

before the power device is turned on. If input

voltage goes above 5.8V, the output voltage will

be limited at 5.8V with fast response.

APPLICATIONS

•

HDD, SSD

Hot Swap Systems

Gaming

Set-top Boxes/Smart TV

PCIe Cards

Switches/Routers

The EN/Fault pin is a bi-directional, three-level

I/O with a weak pull-up. It can be used to

enable or disable MP5018, or indicate a fault

condition.

The device is available in a QFN12 (2mmx3mm)

package.

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.
