MIC4451CT

Overview

The MIC4451CT is a low-side MOSFET gate driver manufactured by Microchip Technology, housed in an 8-pin SOIC package. It delivers a peak output current of 12 A and operates within a supply voltage range of 4.5 V to 18 V. The device features an inverting configuration with rise and fall times of 25 ns. It supports CMOS logic inputs and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

Provides high peak output current capability for driving large MOSFETs
Features matched rise and fall times for efficient switching performance
Accepts logic inputs from 2.4V to VS without external speed-up components
Includes protection against electrostatic discharge damage

Applications

Switch mode power supplies
Motor control systems
Class-D switching amplifiers
Pulse transformer drivers

Procurement Notes

Verify the specific suffix 'CT' against official Microchip documentation to confirm exact packaging or temperature grade specifications. Ensure compatibility with standard SOIC-8 footprints during integration. Confirm RoHS compliance status through current datasheets before final procurement decisions.

Selection Notes

Select this component when a low-side inverting driver with 12 A peak current is required. It is suitable for applications needing fast switching speeds with 25 ns transition times. Consider the 4.5 V to 18 V supply range and -40°C to +85°C operating temperature limits for environmental suitability.

Part Context

This part belongs to the MIC4451/MIC4452 series of CMOS MOSFET drivers. The MIC4451 variant specifically provides an inverting output, whereas the MIC4452 offers non-inverting functionality. Both share similar electrical characteristics including 12 A peak drive capability and BiCMOS/DMOS construction for robustness.

Replacement Considerations

MIC4452VM serves as a functional substitute if a non-inverting configuration is acceptable. TC4451VPA offers similar drive strength but utilizes a PDIP package and extends the operating temperature range to +125°C.
