MIC4428YN

Overview

The MIC4428YN is a dual low-side gate driver IC manufactured by Microchip Technology. It features two independent output channels capable of delivering a peak output current of 1.5 A. The device operates within a supply voltage range of 4.5 V to 18 V and is housed in an 8-pin PDIP package. Key timing parameters include a rise time of 20 ns and a fall time of 20 ns, with a maximum fall time specification of 20 ns. The output interface count is two, supporting both inverting and non-inverting configurations.

Feature Summary

• Dual channel architecture providing independent control for low-side switching applications
• High peak output current capability of 1.5 A for efficient gate drive performance
• Supports both inverting and non-inverting logic input configurations

Applications

• Low-side power switching circuits
• Motor control systems requiring dual channel drive
• Power management modules utilizing MOSFET or IGBT gates

Procurement Notes

Verify the specific ordering suffix and package variant against the official Microchip datasheet to ensure compatibility with the required 8-pin PDIP form factor. Confirm that the operating supply voltage range aligns with system requirements before procurement. Cross-reference the manufacturer part number to distinguish between original Microchip production and any potential distributor-specific markings.

Selection Notes

Select this component when dual independent low-side driving is required with high current capability. Ensure the application logic supports the available inverting and non-inverting options. Verify that the 4.5 V to 18 V supply range fits the system design constraints. Consider the 8-pin PDIP package for through-hole mounting requirements.

Part Context

The MIC4428YN belongs to the family of dedicated gate driver integrated circuits designed for power electronics. It serves as a bridge between low-power control logic and high-power switching devices. As a low-side driver, it is typically used in half-bridge or full-bridge topologies where the load is connected to the positive rail.
