MIC4467YWM

Overview

The MIC4467YWM is a low-side MOSFET gate driver from Microchip Technology, housed in a 16-pin SOIC package. It features four independent drivers with an output current capability of 1.2 A. The device operates within a supply voltage range of 4.5 V to 18 V and supports inverting logic configuration. Electrical performance includes rise and fall times of 25 ns. The component is rated for commercial temperature operation between 0°C and +70°C.

Feature Summary

• Provides four independent low-side gate drive channels
• Delivers high peak output current for fast switching
• Utilizes CMOS technology for low power consumption
• Supports inverting input logic configuration

Applications

• Power management systems requiring multiple low-side switches
• Motor control applications driving MOSFET arrays
• DC-DC converter topologies utilizing parallel or interleaved phases

Procurement Notes

Verify the specific suffix indicates tube packaging rather than tape-and-reel variants. Confirm RoHS compliance status as indicated in official documentation. Ensure the operating temperature range meets the application requirements, as commercial grades differ from industrial specifications. Cross-reference the datasheet revision to confirm pinout and electrical characteristics match the design intent.

Selection Notes

Select this component when four isolated low-side drives are required in a compact surface-mount form factor. The 1.2 A output current suits standard power MOSFETs. Verify that the inverting logic aligns with the control signal polarity. Consider thermal dissipation capabilities if driving high-capacitance loads at elevated frequencies.

Part Context

This part belongs to the MIC4467 series of Power Logic CMOS Quad Drivers. It serves as a low-side alternative to high-side or half-bridge drivers. The family typically includes variants with different packaging options and temperature ratings. The YWM suffix specifically denotes the SOIC-16 package type used in this configuration.

Replacement Considerations

The MIC4467CWM is a related variant within the same series but may differ in temperature rating and packaging. Verify compatibility regarding operating temperature ranges and physical footprint before substitution.
