Overview
The MIC4426BM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features independent channels with peak output currents of 1.5A source and 1.5A sink. The device operates on a supply voltage range of 4.5V to 18V and supports logic input thresholds of 0.8V (VIL) and 2.4V (VIH). Typical rise and fall times are 20ns and 29ns, respectively. It is housed in an 8-SOIC package and functions as an inverting driver for N-channel and P-channel MOSFETs across a junction temperature range of -40°C to 150°C.
Feature Summary
- Dual independent channel configuration for simultaneous control of two low-side switches
- High peak drive current capability of 1.5A for both sourcing and sinking operations
- Robust thermal performance supporting operation up to 150°C junction temperature
- Compatible with standard logic levels through defined VIL and VIH thresholds
Applications
- DC/DC converter synchronous rectification
- Motor control bridge drivers
- Power management circuits requiring low-side switching
Procurement Notes
Verify the specific suffix 'BM' indicates the industrial temperature grade and SOIC package variant when ordering. Confirm that the '-TR' suffix denotes tape and reel packaging. Ensure compatibility with existing PCB footprints for the 8-SOIC form factor. Cross-reference the manufacturer part number against official Microchip databases to confirm current production status and RoHS compliance before finalizing procurement plans.
Selection Notes
Select this component for applications requiring dual low-side driving with high peak current capabilities. The 1.5A output current is suitable for driving medium-power MOSFETs efficiently. Consider the 8-SOIC package constraints for board space. Verify that the 4.5V minimum supply voltage aligns with the system's available power rails. The inverting logic function must be accounted for in the control signal design.
Part Context
This component belongs to the MIC4426/4427/4428 family of dual low-side MOSFET drivers fabricated on a BiCMOS/DMOS process. This technology ensures low power consumption and high efficiency. The MIC4426 specifically provides two independent channels, distinguishing it from single-channel or four-channel variants within the broader product line.
Replacement Considerations
MIC4426YM-TR serves as a package-compatible alternative using the SOIC-8 footprint. MIC4426BMM offers the same electrical specifications but utilizes an MSOP-8 package, requiring layout adjustments.
