MIC5018YM4-TR

Overview

The MIC5018YM4-TR is a high-side MOSFET driver designed to switch N-channel enhancement-type MOSFETs. It operates within a supply voltage range of +2.7V to +9V and features a typical supply current of 150 μA at a 5V supply. The device accepts TTL-compatible control signals and is housed in a lead-free SOT-143 package with four pins.

Feature Summary

• Designed to drive N-channel enhancement-type MOSFETs for high-side switching applications
• Accepts TTL-compatible control logic inputs for direct interface with standard digital controllers
• Operates reliably across a wide input voltage range from 2.7V to 9V

Applications

• High-side power switching in automotive systems
• Load control in industrial equipment
• Battery management system protection circuits

Procurement Notes

Verify the specific suffix -TR indicates tape and reel packaging when sourcing. Confirm the component matches the Microchip Technology manufacturer identification. Ensure the part number corresponds to the non-inverting high-side driver variant rather than other family members with different logical outputs or packages.

Selection Notes

Select this component when a compact, low-current solution is required for driving N-channel MOSFETs in high-side configurations. The SOT-143 package offers space efficiency for dense PCB layouts. Ensure the load current requirements align with the external MOSFET capabilities, as the driver provides gate charge rather than direct load current.

Part Context

This part belongs to the MIC5018 family of IttyBitty high-side MOSFET drivers. These devices are engineered for cost-sensitive applications requiring minimal footprint. The YM4 designation identifies the specific SOT-143 package configuration used in this product line.
