Overview
The MIC4427YM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It features non-inverting inputs and supports supply voltages from 4.5V to 18V. The device 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 operates within a junction temperature range of -40°C to 150°C and is housed in an 8-SOIC package.
Feature Summary
- Dual independent low-side driver configuration
- Non-inverting logic input compatibility
- High peak current capability for efficient load driving
- Extended thermal operating range
Applications
- Resistive load driving
- Inductive load driving
- MOSFET gate control in power conversion circuits
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to ensure correct packaging and tape specifications. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the datasheet revision history for any recent manufacturing or material changes before finalizing procurement plans.
Selection Notes
Select this component when a non-inverting low-side drive signal is required for dual-channel applications. Ensure the input logic levels align with the specified VIL and VIH thresholds. Consider the 1.5A peak current rating relative to the target MOSFET's gate charge requirements and switching frequency constraints.
Part Context
This part belongs to the MIC4426/4427/4428 series of dual MOSFET drivers. The MIC4427 variant specifically provides non-inverting outputs, distinguishing it from the inverting MIC4426. Both share similar electrical characteristics and packaging options, allowing for design flexibility based on control logic polarity needs.
Replacement Considerations
The MIC4426YM-TR serves as a functional substitute if inverting logic is acceptable. Verify pinout compatibility and electrical parameter alignment before substitution. No other direct cross-model replacements are confirmed in public documentation.
