MIC94084YFT-TR Microchip

MIC94080/1/2/3/4/5 67 m R 2A High-Side Load Switch DS(ON) in 0.85 mm x 0.85 mm FTDFN Package Features General Description Space-Saving 0.85 mm x 0.85 mm 4-Lead The MIC94080/1/2/3/4/5 is a family of high-side load FTDFN Package switches designed to operate from 1.7V to 5.5V input voltage. The load switch pass element is an internal Input Voltage Range: 1.7V to 5.5V 67 m R P-Channel MOSFET that enables the DS(ON) 2A Continuous Operating Current device to support up to 2A of continuous current. 67m R DS(ON) Additionally, the load switch supports 1.5V logic level Internal Level Shift for CMOS/TTL Control Logic control and shutdown features in a tiny 0.85 mm x Ultra-Low Quiescent Current 0.85 mm 4-lead FTDFN package. Micropower Shutdown Current The MIC94080 and MIC94081 feature rapid turn on. Soft-Start: MIC94082/3 (800 s), MIC94084/5 The MIC94082 and MIC94083 provide a slew rate (120 s) controlled soft-start turn-on of 800 s, while the MIC94084 and MIC94085 provide a slew rate Load Discharge Circuit: MIC94081, MIC94083, controlled soft-start turn-on of 120 s. The soft-start MIC94085 feature is provided to prevent an in-rush current event Ultra-Fast Turn-Off Time from pulling down the input supply voltage. 40C to +125C Junction Operating Temperature The MIC94081, MIC94083, and MIC94085 feature an Applications active load discharge circuit which switches in a 250 load when the switch is disabled to automatically Cellular Phones discharge a capacitive load. Portable Navigation Devices (PND) An active pull-down on the enable input keeps the Personal Media Players (PMP) MIC94080/1/2/3/4/5 in a default OFF state until the Ultra-Mobile PCs enable pin is pulled above 1.25V. Internal level shift Portable Instrumentation circuitry allows low voltage logic signals to switch Other Portable Applications higher supply voltages. The enable voltage can be as high as 5.5V and is not limited by the input voltage. PDAs GPS Modules The MIC94080/1/2/3/4/5 operating voltage range makes them ideal for Lithium ion and Industrial and Datacom Equipment NiMH/NiCad/Alkaline battery powered systems, as well Package Type as non-battery powered applications. The devices provide low quiescent current and low shutdown MIC94080/1/2/3/4/5 current to maximize battery life. 4-Lead 0.85 mm x 0.85 mm FTDFN (Top View) 2019 Microchip Technology Inc.
