MIC4469ZWM-TR

Overview

The MIC4469ZWM-TR is a low-side gate driver IC manufactured by Microchip Technology, housed in a 16-SOIC surface-mount package. It features four independent drivers with non-inverting input logic. The device operates on a supply voltage range of 4.5V to 18V and supports MOSFETs including N-channel and P-channel types. Peak output current capability is 1.2A for both sourcing and sinking. Typical rise and fall times are 25ns each. The component functions within an operating temperature range of 0°C to 70°C and has a logic threshold VIL of 0.8V and VIH of 2.4V.

Feature Summary

• Provides four independent low-side gate drive channels for power switching applications
• Supports both N-channel and P-channel MOSFET loads with symmetrical peak output currents
• Features fast switching characteristics with typical rise and fall times of 25 nanoseconds
• Operates with standard CMOS logic levels using defined input voltage thresholds

Applications

• Driving low-side N-channel and P-channel MOSFETs in power conversion circuits
• Interface between microcontrollers and power switches in motor control systems
• General-purpose gate driving for isolated or non-isolated power electronics

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging when ordering. Confirm the Z suffix corresponds to the commercial temperature grade (0°C to 70°C) rather than industrial variants. Ensure the 16-SOIC footprint matches the target PCB design. Check RoHS compliance status as per the latest manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when four independent low-side drivers are required in a compact SOIC package. It is suitable for applications needing 1.2A peak drive current with moderate switching speeds. Consider the commercial temperature range limits if operation exceeds 70°C. Compare against MIC4468 series variants if different timing characteristics or industrial temperature ratings are necessary for the specific system requirements.

Part Context

This part belongs to the MIC4467/4468/4469 family of quad gate drivers from Microchip Technology. These devices are designed for driving power MOSFETs in various power management and motor control applications. The MIC4469 variant specifically offers non-inverting logic configuration. The family shares similar electrical characteristics but may differ in temperature grades or specific timing parameters.

Replacement Considerations

MIC4468ZWM-TR is a related variant within the same family offering similar functionality. Verify compatibility regarding temperature range and exact switching times before substitution. Other members of the MIC446x series may serve as alternatives depending on specific inverting/non-inverting requirements and thermal constraints.
