Overview
The MIC4426YMM-TR is a low-side gate driver IC manufactured by Microchip Technology, housed in an 8-MSOP surface-mount package. It features two independent channels with inverting logic inputs, designed to drive N-channel and P-channel MOSFETs. The device operates on a supply voltage range of 4.5V to 18V and delivers peak output currents of 1.5A for both sourcing and sinking. Typical rise and fall times are 20ns and 29ns, respectively. Logic thresholds are defined at 0.8V (VIL) and 2.4V (VIH). It supports a junction temperature range from -40°C to 150°C.
Feature Summary
- Provides dual independent low-side driving capability for power switches
- Features inverting input logic compatible with CMOS and TTL standards
- Delivers high peak current output of 1.5A for rapid MOSFET switching
- Operates reliably across an extended industrial temperature range
Applications
- DC-DC converter synchronous rectification control
- Motor driver bridge circuits
- Inverter systems requiring low-side switching
- Power supply management modules
Procurement Notes
Verify the specific suffix 'YM' corresponds to the MSOP package variant when ordering. Confirm RoHS3 compliance status as per the latest manufacturer documentation. Ensure ESD handling protocols are followed during assembly due to the sensitive CMOS input structure. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.
Selection Notes
Select this component for applications requiring dual low-side drive with inverting logic. Compare against MIC4427YM-TR if non-inverting functionality is required instead. Consider the MIC4426YM-TR if a wider SOIC footprint is acceptable for thermal or mechanical reasons. Verify that the 1.5A peak current meets the gate charge requirements of the target MOSFETs within the desired switching frequency.
Part Context
This part belongs to the MIC442x family of gate drivers, which includes variants with different logic polarities and packages. The MIC4426 specifically denotes the inverting configuration. It is often used in conjunction with other power management components to create efficient switching stages. The TR suffix indicates tape and reel packaging for automated assembly processes.
Replacement Considerations
MIC4427YM-TR offers identical electrical characteristics but with non-inverting logic. MIC4428YM-TR provides a non-inverting configuration similar to the MIC4427. For package alternatives, the MIC4426YM-TR uses an 8-SOIC housing instead of the 8-MSOP form factor while maintaining the same pinout and performance.
