MIC20XX Family Fixed and Adjustable Current Limiting Power Distribution Switches General Description Features MIC20XX family of switches are current limiting, high-side MIC20X3 MIC20X9 power switches, designed for general purpose power 70m typical on-resistance 5V distribution and control in digital televisions (DTV), printers, MIC2005A/20X9A set top boxes (STB), PCs, PDAs, and other peripheral 170m typical on-resistance 5V devices (see Functionality Table and Pin Configuration Enable active high or active low drawings) 2.5V 5.5V operating range MIC20XX familys primary functions are current limiting and power switching. They are thermally protected and will Pre-set current limit values of 0.5A, 0.8A, and 1.2A* shutdown should their internal temperature reach unsafe Adjustable current limit 0.2A to 2.0A* (MIC20X7- levels, protecting both the device and the load, under high- MIC20X9) current or fault conditions Adjustable current limit 0.1A to 0.9A* (MIC20X9A) Features include fault reporting, fault blanking to eliminate Undervoltage lock-out (UVLO) noise-induced false alarms, output slew rate limiting, under Variable UVLO allows adjustable UVLO thresholds* voltage detection, automatic-on output, and enable pin Automatic load discharge for capacitive loads* with choice of either active low or active high enable. The FET is self-contained, with a fixed- or user-adjustable Soft-start prevents large current inrush current limit. The MIC20XX family is ideal for any system Adjustable slew rate allows custom slew rates* where current limiting and power control are desired. Automatic-on output after fault The MIC201X (3 x 9) and MIC2019A switches offer a Thermal protection unique new patented feature: Kickstart, which allows momentary high-current surges up to the secondary * Available on some family members current limit (I 2nd) without sacrificing overall system LIMIT safety. Applications The MIC20xx family is offered, depending on the desired Digital televisions (DTV) features, in a space-saving 5-pin SOT-23, 6-pin SOT-23, Set top boxes and 2mm x 2mm MLF packages.
