MP5000A

12V, 5A Programmable Current

Limit Switch

The Future of Analog IC Technology

DESCRIPTION

FEATURES

•

Integrated 40mΩ Power FET

Enable/Fault Pin

The MP5000A is a protection device designed to

protect circuitry on the output (source) from

transients on input (V_CC). It also protects V_CCfrom

undesired shorts and transients coming from the

source.

Adjustable Slew Rate for Output Voltage

Adjustable Current Limit: 1-5A

Thermal Protection

Over Voltage Limit

Low Inrush Current

At start up, inrush current is limited by limiting the

slew rate at the source. The slew rate is

controlled by a small capacitor at the dv/dt pin.

The dv/dt pin has an internal circuit that allows

the customer to float this pin (no connect) and

still receive 0.9ms ramp time at the source.

APPLICATIONS

•

Hot Swap

PC Cards

Laptops

The maximum load at the output (source) is

current limited. This is accomplished by utilizing a

sense FET topology. The magnitude of the

current limit is controlled by an external resistor

from the I-Limit pin to the Source pin.

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.

An internal charge pump drives the gate of the

power device, allowing a very low on-resistance

DMOS power FET of just 40mΩ.

The source is protected from the V_CCinput being

too low or too high. Under Voltage Lockout

(UVLO) assures that V_CCis above the minimum

operating threshold, before the power device is

turned on. If V_CCgoes above the high output

threshold, the source voltage will be limited.
