MIC4605-1YM-TR

Overview

The MIC4605-1YM-TR is an 85V half-bridge MOSFET gate driver manufactured by Microchip Technology. It operates with a supply voltage range of 5.5V to 16V and features adaptive dead-time control alongside shoot-through protection. The device utilizes an 8-lead SOIC surface-mount package and supports input logic levels of 0.8V (VIL) and 2.2V (VIH). It provides peak output currents of 1A for both sourcing and sinking, with typical rise and fall times of 20ns. The component is qualified under AEC-Q100 standards and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

• Adaptive dead-time circuitry actively monitors half-bridge outputs to minimize transition time between high-side and low-side MOSFETs, maximizing power efficiency.
• Integrated shoot-through protection prevents simultaneous conduction of both MOSFETs caused by erroneous inputs or noise.
• Dual independent inputs allow flexible configuration for half-bridge driving applications.

Applications

• High-efficiency DC-DC converter designs requiring precise switching control
• Industrial motor drive systems utilizing half-bridge topologies
• Automotive power electronics compliant with AEC-Q100 reliability standards

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm that the 8-SOIC package dimensions match your PCB footprint requirements. Ensure the design accounts for the 85V maximum bootstrap voltage rating. Check current availability status as distribution channels may vary for this specific part number.

Selection Notes

Select this component when an 85V half-bridge driver with integrated adaptive timing is required. It is suitable for applications needing robust shoot-through prevention without external timing components. Consider the 8-SOIC package constraints and the 5.5V to 16V supply range during system design. Verify compatibility with the target MOSFET gate charge requirements against the 1A peak drive capability.

Part Context

The MIC4605 series represents a family of 85V half-bridge MOSFET drivers designed for high-performance power conversion. Originally developed by Micrel Semiconductor, the product line was integrated into Microchip Technology's portfolio following acquisition. The MIC4605-1YM-TR specifically denotes the version packaged in an 8-lead SOIC format with tape-and-reel delivery, maintaining the core functional specifications of the broader MIC4605 family.
