MIC20XX Family  
Fixed and Adjustable Current Limiting  
Power Distribution Switches  
General Description  
Features  
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)  
MIC20X3 – MIC20X9  
70mΩ typical on-resistance @ 5V  
MIC2005A/20X9A  
170mΩ typical on-resistance @ 5V  
Enable active high or active low  
2.5V – 5.5V operating range  
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  
Pre-set current limit values of 0.5A, 0.8A, and 1.2A*  
Adjustable current limit 0.2A to 2.0A* (MIC20X7-  
MIC20X9)  
Adjustable current limit 0.1A to 0.9A* (MIC20X9A)  
Undervoltage lock-out (UVLO)  
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.  
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  
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.  
Thermal protection  
* Available on some family members  
Applications  
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.  
Digital televisions (DTV)  
Set top boxes  
PDAs  
Printers
