MIC4605-2YMT-T5

Overview

The MIC4605-2YMT-T5 is an 85V half-bridge MOSFET driver from Microchip Technology, housed in a 10-TDFN package. It operates on a supply voltage range of 5.5V to 16V with a typical quiescent current of 135µA. The device features adaptive dead-time circuitry and shoot-through protection. It provides peak output currents of 1A for both sourcing and sinking. Propagation delay is typically 35ns, with rise and fall times of 20ns driving a 1000pF load. It functions within a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.

Feature Summary

• Adaptive dead-time circuitry actively monitors outputs to minimize transition time between high-side and low-side MOSFETs, maximizing power efficiency.
• Shoot-through protection prevents simultaneous conduction of both MOSFETs caused by erroneous inputs or noise.
• Single PWM input configuration simplifies control interface requirements for half-bridge applications.

Applications

• Brushed DC motor drivers
• Power inverters
• High-voltage buck regulators

Procurement Notes

Verify component authenticity through authorized Microchip channels due to the prevalence of counterfeits in the gate driver market. Confirm that the specific suffix T5 corresponds to the required tape-and-reel packaging format for automated assembly processes. Ensure the ordering documentation explicitly states the 10-TDFN package variant to avoid confusion with other MIC4605 pinouts.

Selection Notes

Select this model when a single PWM input is preferred over dual TTL inputs found in other variants. The 10-TDFN package offers a compact footprint suitable for space-constrained designs. Consider the 85V rating for medium-voltage half-bridge topologies. Verify that the 1A peak drive current meets the gate charge requirements of the target MOSFETs at the intended switching frequency.

Part Context

This component belongs to the MIC4605 family of half-bridge drivers designed for robust performance in automotive and industrial environments. The series integrates advanced protection features to enhance system reliability. The T5 suffix indicates a specific reel quantity and packaging style distinct from cut-tape or tray options available for other part numbers in the same family.

Replacement Considerations

Direct substitutes include MIC4605-2YM-TR and MIC4605-2YMT-TR, which share identical electrical characteristics but may differ in packaging format. Verify pin compatibility and thermal performance when transitioning between different package types within the same functional family.

FAQ

How does the adaptive dead-time feature function?

The adaptive dead-time circuitry actively monitors the half-bridge outputs to dynamically adjust the delay between high-side and low-side transitions, minimizing overlap and maximizing efficiency.

What is the input logic type for the MIC4605-2YMT-T5?

The MIC4605-2YMT-T5 utilizes a single PWM input configuration, distinguishing it from the dual TTL input version (MIC4605-1).
