MP5014A

12 V, 5 A, Programmable Current-Limit

Switch with Over-Volatge Clamp and

Slew-Rate Control in TSOT23-8

DESCRIPTION

The MP5014A is a protection device designed to

protect circuitry on the output (source) from

transients on the input (VCC). Also, it protects VCC

from undesired shorts and transients coming

from the source.

At start-up, the inrush current is limited by

restricting the slew rate at the source. The slew

rate is controlled by a small capacitor at DV/DT.

DV/DT has an internal circuit that allows this pin

to float (no connection) and still receive 1 ms

ramp time at the source.

The maximum load at the output 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 I-LIMIT to

SOURCE.

An internal charge pump drives the gate of the

power device, allowing a very low on-resistance

DMOS power FET of just 36 mΩ.

The source is protected from the VCC input going

too low or too high. Under-voltage lockout (UVLO)

assures that VCC is above the minimum operating

threshold before the power device is turned on. If

VCC rises above the high output threshold, the

source voltage is limited.

TSOT23-8 ..............................100 ..... 55 ... °C/W

NOTES:

1) Exceeding these ratings may damage the device.

2) The maximum allowable power dissipation is a function of the

maximum junction temperature TJ(MAX), the junction-to-

ambient thermal resistance θJA, and the ambient temperature

TA. The maximum allowable continuous power dissipation at

any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-

TA)/ θJA. Exceeding the maximum allowable power dissipation

will produce an excessive die temperature, causing the

regulator to go into thermal shutdown. Internal thermal

shutdown circuitry protects the device from permanent

damage.

3) The device is not guaranteed to function outside of its

operating conditions.

4) Measured on JESD51-7, 4-layer PCB.
