MIC2514
IttyBitty™ Integrated High-Side Switch
Preliminary Information
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.
