MP5010

5V, 1A- 5A Programmable Current

Limit Switch

The Future of Analog IC Technology

The Enable/Fault pin allows the IC to be turned

off and enter a low current shutdown state. This

pin is bi-directional and allows feedback of fault

information. Momentary current spikes are not

considered as faults, neither is the momentary

over voltage. However prolonged over current or

over voltage conditions will cause excessive

power dissipation and result in a thermal

shutdown. And the thermal shutdown will cause a

fault condition.

DESCRIPTION

The MP5010 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.

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 1.5ms ramp time at the source.

FEATURES

•

Integrated 44mΩ Power FET

Enable/Fault Pin

Adjustable Slew Rate for Output Voltage

Adjustable Current Limit

Thermal Protection

The max 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.

Over Voltage Limit

An internal charge pump drives the gate of the

power device, allowing a very low on-resistance

DMOS power FET of just 44mΩ.

APPLICATIONS

•

Hot Swap

PC Cards

Laptops

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.
