MIC94080YFT-TR

Product Overview

The MIC94080YFT-TR from Microchip Technology is a single-output high-side power switch with a P-channel output and 1:1 input-to-output ratio. It uses an On/Off, non-inverting interface and operates over a load voltage range of 1.7 V to 5.5 V. The device is rated for 2 A maximum output current and has a typical Rds On of 67 mOhm. It is packaged in a 4-TMLF surface-mount package, 0.85 mm by 0.85 mm, with an operating junction temperature range of -40°C to 125°C.

Key Features

• Single high-side P-channel output with 1:1 input-to-output ratio
• On/Off interface with non-inverting input control

• 2 A maximum output current
• Typical Rds On of 67 mOhm
• 4-TMLF surface-mount package, 0.85 mm by 0.85 mm
• Operating junction temperature range of -40°C to 125°C

Applications

• Switching loads in portable and battery-powered electronics
• Powering or disconnecting peripheral circuits in embedded systems
• Controlling loads in general-purpose power distribution systems

Design & Procurement Notes

For board design, the 4-TMLF package and surface-mount format require compact land-pattern planning and attention to thermal behavior near the 125°C junction limit. The 1.7 V to 5.5 V load range and 2 A output current define the switching envelope, while the 67 mOhm typical Rds On should be considered for conduction losses. The On/Off, non-inverting interface simplifies basic load-control logic, and the high-side P-channel output should be matched to the intended supply and load topology.
