MIC4417YM4-TR

Overview

The MIC4417YM4-TR is a low-side gate driver IC from Microchip Technology's IttyBitty series, designed for driving high-speed MOSFETs and IGBTs. It features a single channel with inverting input logic. The device operates on a supply voltage range of 4.5V to 18V and supports logic levels with VIL of 0.8V and VIH of 2.4V. It delivers a peak output current of 1.2A for both sourcing and sinking. Typical rise and fall times are 14ns and 16ns, respectively. The component is housed in a SOT-143 surface-mount package and functions within a junction temperature range of -40°C to 150°C.

Feature Summary

• Provides non-isolated low-side drive capability for power switching applications
• Features inverting logic input configuration for signal control
• Delivers high peak output current suitable for fast-switching MOSFETs and IGBTs

Applications

• Driving high-speed N-channel MOSFETs in power conversion circuits
• Gate drive stages for IGBT-based inverters and motor drives
• Low-side switching control in DC-DC converter topologies

Procurement Notes

Verify the specific suffix 'YM4' corresponds to the SOT-143 package variant when sourcing. Confirm that the 'TR' designation indicates tape-and-reel packaging for automated assembly processes. Ensure compatibility with the required operating temperature range of -40°C to 150°C for the target application environment. Cross-reference the datasheet revision date to ensure compliance with current electrical specifications.

Selection Notes

Select this component when a compact, low-side driver with inverting logic is required for high-current switching applications. The SOT-143 package offers space efficiency compared to larger footprints. Consider the 1.2A peak current capability for driving moderate-capacitance loads. Verify that the inverting input behavior aligns with the system's control logic requirements before integration into the design.

Part Context

This part belongs to the MIC4416/MIC4417 family of low-side gate drivers. The MIC4416 variant provides non-inverting logic, whereas the MIC4417 specifically offers inverting functionality. Both share similar electrical characteristics and package options, differing primarily in input-output relationship. This family is part of Microchip's IttyBitty series, emphasizing small form factor solutions for power management.

Replacement Considerations

• MIC4416YM4-TR (Non-inverting equivalent)
• MIC4417SM4-TR (Same function, different package)
