5V, 1A- 5A Programmable Current

Limit Switch with Slew Rate Control and

Auto Enable

DESCRIPTION

The MP5006 is a protection device designed to

protect circuitry on the output (VOUT) from

transients on input (VIN). It also protects VIN from

undesired shorts and transients coming from the

load.

At start up, inrush current is controlled by limiting

the slew rate at the VOUT. 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 a 1.1ms ramp time at the VOUT.

The max load at the output (VOUT) is current

limited. This is accomplished by utilizing a sense

FET topology. The magnitude of the current limit

is controlled by an external resistor connected

between the ILIMIT pins.

An internal charge pump drives the gate of the

power device, allowing a very low on-resistance

DMOS power FET of just 0.044Ω.

VOUT is protected from VIN being too low or too

high. Under Voltage Lockout (UVLO) assures

that the input is above the minimum operating

threshold, before the power device is turned on.

If VIN goes above the high output threshold, the

output voltage will be limited.
