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 on page 6 and Pin
Configuration Drawings on page 8.
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
x
9) and MIC2019A switches offer a
unique new patented feature: Kickstart™, which allows
momentary high current surges up to the secondary
current limit (ILIMIT_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.
