MIC4428ZM

Overview

The MIC4428ZM is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features two independent channels with inverting and non-inverting inputs, supporting peak output currents of 1.5A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V and accepts logic levels defined by VIL of 0.8V and VIH of 2.4V. Typical rise and fall times are 20ns and 29ns, respectively. It is housed in an 8-SOIC package (3.90mm width) and supports operation over a junction temperature range of -40°C to 150°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• Integrated inverting and non-inverting input configurations for flexible signal interfacing
• High-speed switching capability with typical transition times under 30ns
• Robust thermal performance supporting extended industrial junction temperatures up to 150°C

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring independent phase drive
• Power management systems utilizing N-channel and P-channel MOSFETs
• Industrial automation power stages

Procurement Notes

Verify the suffix 'ZM' corresponds to the specific 8-SOIC package variant and commercial/industrial temperature grade (-40°C to 150°C). Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required tape-and-reel or tube packaging configuration if applicable, as availability may vary by distribution channel.

Selection Notes

Select this component when dual independent low-side driving is required with mixed polarity inputs. The 1.5A peak current rating suits medium-power MOSFET applications. Compare against the MIC4427 series if only non-inverting inputs are needed, or the MIC4468 series for quad-channel requirements. Validate that the 4.5V minimum supply voltage aligns with the system's available rail.

Part Context

The MIC4428 belongs to the MIC442x family of high-speed MOSFET drivers from Microchip Technology, formerly Micrel. This family includes variants like the MIC4426, MIC4427, and MIC4428, differentiated primarily by input logic types (inverting vs. non-inverting) and channel counts. The ZM suffix denotes the SOIC package option within this product line.
