MIC20XX Family

Fixed and Adjustable Current Limiting

Power Distribution Switches

General Description

Features

• 70mΩ typical on-resistance @ 5V

• 170mΩ typical on-resistance @ 5V (MIC2005A)

• Enable active high or active low *

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.

• 2.5V – 5.5V operating range

• Pre-set current limit values of 0.5A, 0.8A, and 1.2A *

• User adjustable current limit from 0.2A to 2.1A *

• Under voltage lock-out (UVLO)

• Variable UVLO allows adjustable UVLO thresholds *

• Automatic load discharge for capacitive loads *

• Soft start prevents large current inrush

• Adjustable slew rate allows custom slew rates *

• Automatic-on output after fault

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.

• Thermal Protection

* Available on some family members

Applications

The MIC201X (3 ≤ x ≤ 9) subfamily offers 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.

• Digital televisions (DTV)

• Set top boxes

• PDAs

• Printers

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.

• USB / IEEE 1394 power distribution

• Desktop and laptop PCs

• Game consoles

Micrel’s web site at www.micrel.com.

• Docking stations
