MIC4468CN

Overview

The MIC4468CN is a quad low-side MOSFET gate driver manufactured by Microchip Technology. It features four independent channels designed to drive N-channel and P-channel power MOSFETs. The device operates within a supply voltage range of 4.5V to 18V. It provides peak output currents of 1.2A for both sourcing and sinking. The typical rise and fall times are 14ns and 13ns, respectively. It is housed in a 14-DIP package with a width of 0.300 inches (7.62mm). The component supports inverting and non-inverting input types.

Feature Summary

• Provides four independent low-side driving channels for power MOSFET control
• Capable of delivering 1.2A peak source and sink current for fast switching
• Supports both inverting and non-inverting logic input configurations
• Operates reliably across an extended temperature range from -40°C to 85°C

Applications

• Power management systems requiring multiple low-side switch control
• Motor drive circuits utilizing N-channel or P-channel MOSFETs
• Industrial automation equipment with isolated gate driving needs
• DC-DC converter topologies requiring synchronous rectification

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with existing PCB footprints. Confirm that the 14-DIP form factor matches the target assembly requirements. Check for RoHS compliance status as older revisions may differ. Ensure the operating voltage range aligns with the system's logic levels. Validate lead times due to potential obsolescence or limited production runs.

Selection Notes

Select this component when multiple independent low-side drivers are required in a single package. The 1.2A peak current capability suits standard power MOSFET applications. Consider the 14-DIP package for through-hole prototyping or legacy board designs. Verify that the 4.5V to 18V supply range meets the system's power constraints. Evaluate the 14ns/13ns switching speeds against the required frequency performance.

Part Context

The MIC4468CN belongs to the MIC4468 family of quad low-side MOSFET drivers. It was originally developed by Micrel Semiconductor before being acquired by Microchip Technology.
