MIC4609YWM

Overview

The MIC4609YWM-TR is a six-channel half-bridge gate driver manufactured by Microchip Technology, designed for high-voltage power switching applications. It features three independent channels capable of driving IGBTs and MOSFETs with peak output currents of 1A source and sink. The device operates with a supply voltage range of 10V to 20V and supports bootstrap voltages up to 600V. It utilizes a non-inverting input logic interface with defined thresholds of 0.8V and 2.2V. Typical rise and fall times are 20ns, ensuring fast switching performance. The component is housed in a 28-SOIC package and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Provides three independent half-bridge driver channels for high-side and low-side switching control
• Supports high-voltage operation with a maximum bootstrap voltage rating of 600V
• Delivers symmetrical 1A peak source and sink current capability for efficient gate charging
• Features non-inverting logic inputs compatible with standard digital control interfaces

Applications

• Industrial motor drives and servo systems
• High-voltage inverter circuits
• Switched-mode power supplies (SMPS)
• IGBT and MOSFET gate control in power electronics

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the part status as discontinued or obsolete through official Microchip channels prior to design finalization. Ensure compatibility with existing PCB footprints for the 28-SOIC package. Check for available development tools or selector guides for circuit validation. Validate RoHS compliance status against current regulatory requirements for your target market.

Selection Notes

Select this component when designing circuits requiring isolated high-side drive for voltages up to 600V. Consider the 1A output current sufficient for medium-power IGBTs and MOSFETs. Evaluate the 28-SOIC package size against board space constraints. Verify that the 10V-20V supply range aligns with your system's available rail. Assess thermal management needs given the 125°C junction temperature limit.

Part Context

The MIC4609 belongs to Microchip's MIC4600 series of half-bridge gate drivers. This family includes variants like the MIC4600 and MIC4608, offering different channel counts and package options. The MIC4609 specifically provides three channels in a 28-pin SOIC format, distinguishing it from single or dual-channel alternatives in the same product line.

Replacement Considerations

Official documentation indicates the MIC4608YM-TR and MIC4609YWM-TR were subject to obsolescence notices. No direct functional substitute part numbers are explicitly confirmed in the provided public data. Engineers should consult Microchip directly for qualified replacement recommendations or updated product lines.
