MIC4429CN

Overview

The MIC4429CN is a single-channel, low-side MOSFET gate driver manufactured by Microchip Technology. It provides high peak output current of 6 A for both sourcing and sinking to rapidly switch power devices. The device operates within a supply voltage range of 4.5 V to 18 V and features an inverting logic configuration. Key timing parameters include rise and fall times of 25 ns. It is housed in an 8-pin PDIP package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Delivers 6 A peak source and sink current for fast switching
• Compatible with CMOS and TTL logic inputs
• Supports N-channel and P-channel MOSFET driving

Applications

• Driving N-channel and P-channel power MOSFETs
• Driving IGBTs in power conversion circuits
• Low-side switching applications in motor control

Procurement Notes

Verify the specific suffix 'CN' corresponds to the 8-PDIP through-hole package and commercial temperature range. Confirm RoHS compliance status as detailed in the official datasheet. Ensure the ordering part number matches the required pinout and physical dimensions for your PCB footprint.

Selection Notes

Select this component when a single-channel, low-side driver with 6 A capability is required. It is suitable for applications needing fast switching speeds with 25 ns transition times. Consider the PDIP-8 package if through-hole mounting is necessary for the design.

Part Context

This part belongs to the MIC4429 family of high-speed MOSFET drivers. It is functionally similar to other variants like the TC4429 series but differs in packaging and specific thermal ratings. The CN suffix specifically denotes the plastic dual in-line package format.

Replacement Considerations

Direct substitutes include the TC4429COA (SOIC-8) and TC4429CPA (PDIP-8). Verify pin compatibility and thermal performance before substitution.
