UCC27423P

Gate Driver Overview

The UCC27423P is a dual low-side MOSFET gate driver manufactured by Texas Instruments, housed in an 8-pin PDIP through-hole package. It delivers a peak output current of 4 A with a supply voltage range of 4 V to 15 V. The device features inverting logic inputs compatible with TTL and CMOS standards. Typical switching performance includes a rise time of 20 ns and a fall time of 15 ns under a 1.8-nF load. It operates within a temperature range of -40°C to +105°C and consumes 1.35 mA of quiescent current.

Gate Driver Feature Summary

• Features dedicated enable pins for each driver channel to control operation independently.
• Utilizes a unique Bipolar and CMOS hybrid output stage to provide high current at Miller thresholds.
• Designed with industry-standard pin-out configuration for easy integration.

Gate Driver Applications

• Switch-Mode Power Supplies
• DC/DC Converters
• Motor Controllers

Gate Driver Procurement Notes

Verify the specific suffix 'P' corresponds to the PDIP-8 through-hole package variant when sourcing. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the ordering part number matches the exact manufacturer designation from Texas Instruments to avoid receiving alternative package styles or non-compliant revisions.

Gate Driver Selection Notes

Select this component when a dual low-side driver with industry-standard pinout is required. The PDIP-8 package suits prototyping or applications utilizing through-hole technology. Consider the 4-A drive capability and 20-ns rise time for general-purpose MOSFET switching needs where thermal constraints are manageable within the standard plastic package.

Gate Driver Part Context

This device belongs to the UCC27423/4/5 family of high-speed dual MOSFET drivers. While the UCC27423P specifically denotes the PDIP-8 package, other variants like the SOIC-8 (UCC27423D) or thermally enhanced MSOP (UCC27423MDREP) offer different form factors. All members share identical electrical characteristics and functionality.

Gate Driver Replacement Considerations

Direct functional equivalents include the UCC27423D (SOIC-8 package) and UCC27423MDREP (MSOP-8 package). For automotive applications requiring AEC-Q100 qualification, consider the UCC27423QDRQ1 variant instead.
