MIC4424ZN

Overview

The MIC4424ZN is a dual low-side MOSFET gate driver manufactured by Microchip Technology in an 8-pin PDIP package. It provides non-inverting outputs with a peak output current of 3 A. The device operates within a supply voltage range of 4.5 V to 18 V and supports TTL logic inputs. Key timing parameters include a rise time of 28 ns, a fall time of 32 ns, and maximum on/off delay times of 33 ns. It functions within a temperature range of 0°C to +70°C, consumes 2 mA of operating supply current, and has a power dissipation rating of 960 mW.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High-speed switching capability with nanosecond-level rise and fall times
• TTL-compatible input logic for direct interfacing with standard digital controllers
• Non-inverting signal configuration maintaining input-output phase alignment

Applications

• Low-side switching in DC-DC converter topologies
• Motor control circuits requiring dual MOSFET drive signals
• Power supply designs utilizing synchronous rectification
• Inverter bridge legs where low-side commutation is required

Procurement Notes

Verify the specific suffix 'ZN' corresponds to the PDIP-8 through-hole package variant when sourcing. Confirm that the commercial grade temperature range (0°C to +70°C) meets the operational environmental requirements of the target application. Ensure compatibility with the 4.5 V to 18 V supply voltage window during system design validation.

Selection Notes

Select this component when a dual low-side driver with 3 A peak current is required in a through-hole package. It is suitable for applications needing TTL logic compatibility and non-inverting outputs. Consider alternative packages like SOIC-8 if surface mount technology is preferred, or industrial grade variants if extended temperature ranges beyond +70°C are necessary for the specific deployment environment.

Part Context

The MIC4424ZN belongs to the MIC4424 series of dual MOSFET drivers from Microchip Technology. This series is designed to provide robust gate drive signals for power MOSFETs. The 'ZN' suffix specifically denotes the plastic dual in-line package with a .300-inch lead spacing, distinguishing it from surface-mount options like the YM variant.

Replacement Considerations

The MIC4424YM serves as a pin-compatible surface-mount alternative within the same family. Verify that the SOIC-8 package fits the PCB layout constraints if substituting. Ensure the industrial temperature range of other variants aligns with thermal requirements before replacing the commercial grade ZN part.
