MIC4467BWM

Overview

The MIC4467BWM is a low-side MOSFET gate driver from Microchip Technology, housed in a 16-pin SOIC package. It features four independent drivers with an inverting configuration. The device supports a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 1.2 A. Typical rise and fall times are 14 ns and 13 ns, respectively. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides four independent low-side drive channels for power switching applications
• Features inverting logic input configuration for signal control
• Delivers high peak source and sink currents to accelerate MOSFET switching

Applications

• Low-side MOSFET switching in power supplies
• Motor control circuitry
• Industrial power management systems

Procurement Notes

Verify the specific suffix 'BWM' against the official datasheet to confirm the commercial temperature grade (-40°C to +85°C) and SOIC-16 package type. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Selection Notes

Select this component when four independent low-side drivers are required with inverting logic. Compare against non-inverting variants like the MIC4468 series if signal phase inversion is not desired. Verify that the 1.2 A output current meets the gate charge requirements of the target MOSFETs.

Part Context

This part belongs to the MIC4467/4468/4469 family of quad low-side MOSFET drivers. It shares core electrical characteristics with other members of the series but differs in logic configuration (inverting vs. non-inverting) and operating temperature range specifications defined by its suffix.

Replacement Considerations

MIC4467YN is listed as a direct replacement. TC4469CPD and TC4469EPD are noted as similar alternatives.
