MIC4604YM-TR

Overview

The MIC4604YM-TR is an 85V half-bridge MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 5.25V to 16V and features non-inverting inputs. The device provides peak output currents of 1.5A source and 1A sink. Key electrical parameters include typical rise and fall times of 20ns, propagation delays of 39ns, and a maximum dead time of 10ns. It functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Supports high-side driving for N-channel MOSFETs up to 85V bus voltages
• Features fast switching characteristics with 20ns rise/fall times
• Includes programmable gate drive current control via external resistor
• Provides robust protection against shoot-through with fixed dead time

Applications

• Brushless DC (BLDC) motor control systems
• High-voltage power switching circuits
• Industrial inverter drives

Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the supplier is authorized to guarantee component authenticity. Check for any recent Product Change Notices (PCN) regarding package or material updates before finalizing procurement orders.

Selection Notes

Select this component for applications requiring an 85V half-bridge configuration with programmable gate drive strength. It is suitable for designs needing fast switching speeds and integrated shoot-through protection. Consider the SOIC-8 package constraints and thermal requirements for the intended PCB layout. Verify input logic voltage compatibility with the controlling microcontroller or FPGA.

Part Context

This part belongs to the MIC4604 family of half-bridge MOSFET drivers. It is designed to replace legacy Micrel products following Microchip's acquisition. The device integrates high-side and low-side drivers into a single compact package, simplifying the design of medium-power motor drives and inverters compared to discrete solutions.

Replacement Considerations

Direct substitutes may include other 85V half-bridge drivers from Microchip or compatible equivalents from other manufacturers. Verify pinout compatibility and electrical specifications such as supply voltage range and output current capabilities before substitution.
