Overview
The MIC4427ZM-TR is a dual low-side MOSFET gate driver manufactured by Microchip Technology. It operates within a supply voltage range of 4.5V to 18V and delivers peak output currents of 1.5A for both sourcing and sinking. The device features non-inverting inputs with logic thresholds of 0.8V (VIL) and 2.4V (VIH). Typical switching performance includes rise and fall times of 20ns and 29ns, respectively. It is housed in an 8-SOIC package with a width of 3.90mm and supports junction temperatures up to 150°C.
Feature Summary
- Dual independent low-side drive configuration
- Non-inverting input logic compatibility
- High peak current capability for rapid MOSFET switching
- Wide operating temperature range support
Applications
- DC-DC converter synchronous rectification
- Motor control bridge drivers
- Power supply load switches
Procurement Notes
Verify the specific suffix 'ZM' against the manufacturer's latest datasheet to confirm pinout and electrical specifications match design requirements. Ensure the 'TR' designation aligns with the required tape-and-reel packaging format for automated assembly processes. Cross-reference RoHS compliance status with current environmental declarations.
Selection Notes
Select this component when a dual-channel, non-inverting low-side driver is required for N-channel or P-channel MOSFETs. It is suitable for applications needing 1.5A peak drive current within an 8-pin surface-mount footprint. Consider thermal management capabilities if operating near the upper limits of the specified temperature range.
Part Context
This part belongs to the MIC4426/4427/4428 series of high-speed MOSFET drivers from Microchip Technology. The MIC4427 variant specifically provides non-inverting outputs, distinguishing it from the inverting MIC4426. These devices are designed to replace older discrete driver solutions, offering improved switching speeds and reduced board space in power management circuits.
Replacement Considerations
Direct substitutes include the MIC4426YM-TR for inverted logic applications or the MIC4428YM-TR for high-side configurations. Verify that alternative packages maintain the same 8-SOIC dimensions and pin assignments to ensure mechanical compatibility.
