MIC4429CM

Overview

The MIC4429CM is a single-output, low-side MOSFET gate driver manufactured by Microchip Technology. It provides a peak output current of 6A and operates within a supply voltage range of 4.5V to 18V. The device features an inverting logic configuration with matched rise and fall times of 25ns. It accepts CMOS or TTL logic inputs and functions at temperatures from 0°C to +70°C. Packaged in an 8-pin SOIC, it draws 3mA operating current and dissipates up to 470mW.

Feature Summary

• Provides high peak output current capability for efficient MOSFET switching
• Features latch-up protection against reverse output current conditions
• Logic input withstands negative voltage swings up to 5V
• Offers ESD protection rated at 4kV

Applications

• Switch-Mode Power Supplies
• Motor Controls
• Pulse Transformer Driver
• Class D Switching Amplifiers

Procurement Notes

Verify the specific suffix 'CM' indicates the commercial temperature grade (0°C to +70°C) and SOIC-8 package. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the design accounts for the inverting logic configuration and 6A peak drive requirements. Check for moisture sensitivity classification before assembly.

Selection Notes

Select this component when a single-channel, inverting MOSFET driver with 6A peak current is required. It is suitable for applications needing fast switching speeds with 25ns transition times. Consider the 4.5V to 18V supply range and CMOS/TTL compatibility. Verify that the commercial temperature range meets the system's environmental constraints.

Part Context

The MIC4429CM belongs to the TC4429 series of high-speed MOSFET drivers. It is pin-compatible with the TC429 but offers improved CMOS performance. The series is designed to replace bipolar drivers for lower power consumption and higher efficiency. It serves as a dedicated interface between logic controllers and power MOSFETs.

Replacement Considerations

The TC4429CPA and TC4429VOA are direct functional equivalents within the same family. The TC4429EMF713 is also compatible but may have different packaging and thermal characteristics. Verify pinout and electrical specifications match before substitution.
