UCC27324PE4

Gate Driver Overview

The UCC27324PE4 is a dual high-speed low-side MOSFET gate driver manufactured by Texas Instruments, housed in an 8-pin PDIP package. It delivers a peak output current of 4A for both sourcing and sinking. The device operates within a supply voltage range of 4.5V to 15V. Typical switching characteristics include a rise time of 20ns and a fall time of 15ns. It features non-inverting logic inputs compatible with TTL and CMOS standards, ensuring robust noise immunity through hysteretic input thresholds.

Gate Driver Feature Summary

• Provides ±4A peak drive current capability to effectively charge and discharge power MOSFET gates during the Miller plateau region.
• Features hysteretic logic inputs that are independent of the supply voltage, offering superior noise immunity for reliable operation.
• Utilizes a Bi-CMOS output architecture that maintains constant current drive even at lower supply voltages.

Gate Driver Applications

• Switch-mode power supplies
• DC-DC converters
• Motor control systems

Gate Driver Procurement Notes

Verify the specific suffix 'E4' indicates lead-free composition compliant with RoHS standards. Confirm the PDIP-8 package type matches the target PCB footprint requirements. Ensure the operating temperature range aligns with the application environment constraints. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential design changes.

Gate Driver Selection Notes

Select this component when a dual low-side driver with high peak current is required for driving N-channel or P-channel MOSFETs. The non-inverting configuration simplifies control logic interfacing. Consider thermal management solutions if the application demands sustained high-frequency switching or if ambient temperatures approach the maximum junction rating limits specified in the datasheet.

Gate Driver Part Context

This part belongs to the UCC2732x series of high-speed dual MOSFET drivers from Texas Instruments. It shares functional similarities with the UCC27324DR (SOIC-8) and UCC27324P variants, differing primarily in the package style. The series is designed for applications requiring fast switching speeds and high drive strength in compact form factors.

Gate Driver Replacement Considerations

The UCC27324P is a direct pin-compatible alternative in the same PDIP-8 package. For surface-mount applications, the UCC27324DR offers equivalent electrical performance in an SOIC-8 package. Verify that any substitute maintains the 4A peak current rating and 4.5V-15V supply range.
