MIC4426YM

Overview

The MIC4426YM is a high-speed, dual MOSFET driver manufactured by Microchip Technology. It features two independent channels designed to drive N-channel power MOSFETs with low output impedance. The device operates from a supply voltage range of 4.5V to 18V and provides peak output currents of up to 2A source and 3A sink. It includes built-in shoot-through protection to prevent simultaneous conduction in half-bridge configurations.

Feature Summary

• Dual channel architecture for independent control of high-side and low-side MOSFETs
• Integrated shoot-through protection mechanism to ensure safe switching operations
• Low output impedance design for rapid charging and discharging of gate capacitances

Applications

• Half-bridge and full-bridge motor drive circuits
• High-frequency DC-DC converter topologies
• Inverter systems requiring precise gate drive timing

Procurement Notes

Verify the specific suffix 'YM' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with system voltage requirements before procurement. Cross-reference datasheet revisions to confirm pinout consistency.

Selection Notes

Select this component when dual isolated or non-isolated gate driving is required with integrated protection. Evaluate thermal performance based on PCB layout and switching frequency. Confirm input logic levels match the control microcontroller outputs.

Part Context

This part belongs to the MIC44xx series of MOSFET drivers. It is designed for applications requiring fast switching speeds and robust drive capability. The YM suffix typically indicates a specific package configuration and operating temperature range defined by the manufacturer.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Generic replacements may lack identical shoot-through protection characteristics. Verify pin-to-pin compatibility and electrical specifications before implementation.
