Overview
The MIC4428YM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology in an 8-SOIC package. It provides independent inverting and non-inverting outputs with a peak output current of 1.5A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 18V and supports logic input levels of 0.8V (VIL) and 2.4V (VIH). Typical switching performance includes a rise time of 20ns and a fall time of 29ns. It functions reliably across a junction temperature range of -40°C to 150°C.
Feature Summary
- Provides independent inverting and non-inverting drive configurations for flexible control applications.
- Delivers high peak output current capability of 1.5A for efficient MOSFET switching.
- Includes latch-up protection against reverse current conditions exceeding 500mA.
Applications
- Low-side MOSFET driving in power conversion circuits
- Industrial motor control systems requiring independent phase control
- DC-DC converter topologies utilizing N-channel and P-channel MOSFETs
Procurement Notes
Verify the specific suffix 'YM' indicates the 8-SOIC package variant when ordering. Confirm that the '-TR' suffix denotes tape and reel packaging, which differs from cut tape or tube options available for other variants. Ensure the application requires both inverting and non-inverting channels, as single-channel alternatives exist within the same family. Cross-reference the datasheet for any recent manufacturing site changes or packing updates documented in Product Change Notices.
Selection Notes
Select this component when a single IC must drive two low-side switches with opposite logic polarities. The 1.5A peak current rating suits standard power MOSFETs without external buffering. Consider the 8-SOIC footprint for PCB layout constraints. Verify that the 4.5V minimum supply voltage aligns with the system's logic level requirements. This part is distinct from the MIC4427, which lacks the inverting channel.
Part Context
The MIC4428 belongs to the MIC442x series of low-side gate drivers from Microchip Technology, formerly Micrel. It complements the MIC4426 (single inverting) and MIC4427 (single non-inverting) by combining both functionalities in one package. The YM designation specifically refers to the 8-pin Small Outline Integrated Circuit (SOIC) physical form factor with a 3.90mm width.
Replacement Considerations
MIC4428YMM-TR serves as a pin-compatible alternative in an MSOP-8 package. For single-channel needs, MIC4426YM-TR (inverting) or MIC4427YM-TR (non-inverting) may be suitable if only one output is required. Verify thermal performance differences between SOIC and MSOP packages if space is constrained.
