MIC4467CN

Gate Driver Overview

The MIC4467CN is a low-side MOSFET gate driver from the Microchip Technology MIC4467 family. It integrates four independent CMOS buffer drivers, each equipped with a two-input NAND logic gate for enhanced control flexibility. The device provides a peak output current of 1.2 A and operates within a supply voltage range of 4.5 V to 18 V. It features symmetrical rise and fall times of 25 ns, with maximum on and off delay times of 75 ns. Designed for through-hole mounting in a PDIP-14 package, it supports an operating temperature range from 0°C to +70°C.

Gate Driver Feature Summary

• Integrates four high-power drivers with dedicated two-input NAND logic gates per channel
• Provides robust latch-up resistance capable of withstanding significant ground noise spikes
• Capable of handling reverse current on driver outputs to protect against inductive kickback

Gate Driver Applications

• Driving all four MOSFETs in an H-bridge configuration
• Direct driving of low-current motors
• General-purpose CMOS logic buffering
• Relay or peripheral drivers

Gate Driver Procurement Notes

Verify the specific suffix 'CN' against the manufacturer's official datasheet to confirm the commercial temperature grade (0°C to +70°C) and PDIP-14 through-hole packaging. Ensure compatibility with system requirements regarding the 4.5 V to 18 V supply voltage range and 1.2 A peak drive capability before finalizing procurement.

Gate Driver Selection Notes

Select this component when a quad driver with integrated NAND logic is required to reduce external component count. It is suitable for applications needing fast switching speeds and high peak currents. Consider alternative suffixes if industrial temperature ranges or surface-mount packages are necessary instead of the commercial through-hole version.

Gate Driver Part Context

The MIC4467CN belongs to the TC4467/MIC4467 family of quad MOSFET drivers. These devices expand upon single and dual-output designs by offering four channels in a single package, improving system reliability. The inclusion of onboard logic gates allows these drivers to replace multiple discrete components, simplifying circuit design for power management and motor control applications.

Gate Driver Replacement Considerations

The TC4467CN is a direct functional equivalent within the same product family. Verify that the replacement part matches the PDIP-14 package and commercial temperature specifications.
