MIC94300YMT-TR

Product Overview

The Microchip Technology MIC94300YMT-TR is a general-purpose 1:1 N-channel high-side power switch and load driver intended for low-voltage load control. It provides a single output with an On/Off, non-inverting interface and operates over a 1.8V to 3.6V load voltage range. The device uses a 4-TMLF (1.2x1.6) surface-mount package with an exposed pad, and it supports a maximum output current of 200mA. Fixed current limiting and over-temperature protection are included, and no separate Vcc/Vdd supply is required.

Key Features

• Single-output high-side N-channel switch with a 1:1 input-to-output ratio.
• On/Off control with a non-inverting input and no separate Vcc/Vdd supply.
• 200mA maximum output current for 1.8V to 3.6V load applications.
• Fixed current limiting and over-temperature fault protection.
• Operating junction temperature range of -40°C to 125°C.
• 4-TMLF (1.2x1.6) surface-mount package with exposed pad.

Applications

• Switching a single low-current load in compact surface-mount power paths.
• On/off load control for general-purpose low-voltage distribution circuits.
• High-side load driving where a non-inverting control interface is required.

Design & Procurement Notes

Design reviews should confirm that the high-side N-channel output, 1:1 switching ratio, and 200mA maximum current match the intended load. The 1.8V to 3.6V load range and lack of a separate Vcc/Vdd supply simplify low-voltage control paths, but the non-inverting On/Off interface must be driven appropriately. Fixed current limiting and over-temperature protection should be considered in fault analysis. For layout, verify the 4-TMLF (1.2x1.6) exposed-pad footprint and thermal management within the -40°C to 125°C junction temperature range.
