MIC4422CTL2

Overview

The MIC4422CTL2 is a low-side gate driver IC manufactured by Microchip Technology, housed in a TO-220-5 package. It features a non-inverting logic configuration designed to drive power MOSFETs efficiently. The device supports a wide operating voltage range of 4.5V to 18V and delivers a typical peak output current of 9A. It ensures signal integrity with a minimum pulse width capability of 50ns and includes latch-up protection via a fully isolated process.

Feature Summary

• Non-inverting low-side gate driver architecture for direct control applications
• High peak output current capability of 9A for driving large MOSFET loads
• Latch-up proof construction utilizing a fully isolated manufacturing process
• Wide supply voltage operating range supporting diverse system power requirements

Applications

• Power MOSFET switching in motor control circuits
• Industrial power conversion systems
• Inverter bridge driver stages
• High-frequency switching power supplies

Procurement Notes

Verify the specific suffix CTL2 corresponds to the TO-220-5 through-hole package variant when sourcing. Confirm that the non-inverting logic function aligns with the system design requirements, as the MIC4421 series offers an inverting alternative. Ensure compatibility with the specified 4.5V to 18V supply range for the target application environment.

Selection Notes

Select this component when a robust, high-current low-side driver is required for discrete MOSFETs. The TO-220-5 package provides thermal advantages for higher power dissipation compared to smaller surface-mount options. Consider the non-inverting nature of the MIC4422 if the control signal polarity matches the desired output state without additional inversion logic.

Part Context

This part belongs to the MIC442x family of gate drivers from Microchip Technology, which also includes the inverting MIC4421 variant. The family is characterized by high peak current capabilities and rugged isolation processes suitable for demanding industrial environments. The MIC4422CTL2 specifically denotes the non-inverting version in a through-hole package.

Replacement Considerations

The MIC4421CN or MIC4421CT may serve as substitutes if an inverting logic configuration is acceptable. Other variants within the MIC4422 family, such as MIC4422CM or MIC4422CT, offer different packaging options but share identical electrical characteristics and functionality.
