MIC4609YWM-TR

Overview

The MIC4609YWM-TR is a six-channel half-bridge gate driver manufactured by Microchip Technology, designed for high-voltage applications. It operates within a supply voltage range of 10V to 20V and supports peak output currents of 1A for both sourcing and sinking. The device features non-inverting inputs with logic thresholds of 0.8V and 2.2V. Typical rise and fall times are 20ns. It is housed in a 28-SOIC package and functions across a junction temperature range of -40°C to 125°C.

Feature Summary

• Six-channel configuration for three-phase half-bridge driving
• High-side voltage capability up to 600V via bootstrap
• Compatible with IGBT and N/P-channel MOSFET loads
• Non-inverting input logic interface

Applications

• Three-phase motor control systems
• Industrial inverter drives
• Switched-mode power supplies requiring high-side switching

Procurement Notes

Verify component status as the MIC4609YWM-TR is listed as obsolete or discontinued. Confirm availability through authorized distributors or secondary markets. Check for recent Production Change Notices regarding packaging or testing site updates. Ensure compatibility with replacement components if redesigning for new production runs.

Selection Notes

Select this component for applications requiring simultaneous drive of multiple half-bridges with high voltage isolation capabilities. Consider the 28-SOIC package size for PCB layout constraints. Evaluate thermal performance given the 125°C junction temperature limit. Verify that the 1A peak current meets the gate charge requirements of the target MOSFETs or IGBTs.

Part Context

This part belongs to the MIC4608/MIC4609 family of high-voltage gate drivers. It serves as a multi-channel solution compared to single-channel counterparts like the MIC4422. The YWM suffix indicates the SOIC wide package variant. It complements lower-voltage drivers by offering support for bootstrap circuits up to 600V.
