●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.

●Features

●• 70mΩ typical on-resistance @ 5V

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

●• Enable active high or active low

●• 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

●• Thermal Protection

●Applications

●• Digital televisions (DTV)

●• Set top boxes

●• PDAs

●• Printers

●• USB / IEEE 1394 power distribution
