MIC2003-0.5YML

Manufacturer Part Number
MIC2003-0.5YML
Description
Fixed and Adjustable Current Limiting Power Distribution Switches
Manufacturer
MICREL [Micrel Semiconductor]
Datasheet
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 7.
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) subfamily offers a unique new
patented
momentary high current surges up to the secondary
current limit (I
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
