MIC2514

General Description

The MIC2514 is an integrated high-side power switch that

consists of a TTL compatible input and protected

P-channel MOSFET. The MIC2514 can be used instead of

a separate high-side driver and MOSFET in many low-

voltage applications.

The MIC2514 switches voltage ranging from 3V to 13.5V and

delivers more than 400mA continuous current. A slow turn-

on feature prevents high inrush current when switching

capacitive loads. The internal control circuitry is powered

from the unswitched 3V to 13.5V input.

Current limiting is internally fixed at approximately 1.9A and

requires no external components.

Thermal shutdown turns off the output if the die temperature

exceeds approximately 170 C.

The MIC2514 is available in the 5-lead SOT-23-5 package

with a temperature range of –40 C to +85 C.
