The Future of Analog IC Technology
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 m.
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.

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.
