MIC20XX Family

Fixed and Adjustable Current Limiting

Power Distribution Switches

General Description

MIC20XX family of switches are current limiting, high-side

power switches, designed for general purpose power

distribution and control in digital televisions (DTV), printers,

set top boxes (STB), PCs, PDAs, and other peripheral

devices (see

Functionality Table

and

Pin Configuration

drawings)

MIC20XX family’s primary functions are current limiting

and power switching. They are thermally protected and will

shutdown should their internal temperature reach unsafe

levels, protecting both the device and the load, under high-

current or fault conditions

Features include fault reporting, fault blanking to eliminate

noise-induced false alarms, output slew rate limiting, under

voltage detection, automatic-on output, and enable pin

with choice of either active low or active high enable. The

FET is self-contained, with a fixed- or user-adjustable

current limit. The MIC20XX family is ideal for any system

where current limiting and power control are desired.

The MIC201X (3

≤

9) and MIC2019A switches offer a

unique new patented feature: Kickstart™, which allows

momentary high-current surges up to the secondary

current limit (I

LIMIT

_2nd) without sacrificing overall system

safety.

The MIC20xx family is offered, depending on the desired

features, in a space-saving 5-pin SOT-23, 6-pin SOT-23,

and 2mm x 2mm MLF

packages.
