UCC27425PG4

Gate Driver Overview

The UCC27425PG4 is a dual low-side MOSFET gate driver manufactured by Texas Instruments, housed in an 8-pin PDIP package. It provides independent high-current outputs of 4A peak drive capability for each channel. The device features both inverting and non-inverting logic inputs to accommodate various control schemes. Designed for robust performance, it supports supply voltages from 4V to 18V. The driver includes enable functionality for power management and offers short-circuit protection characteristics. It is optimized for driving N-channel power MOSFETs in applications requiring fast switching speeds and reliable signal integrity.

Gate Driver Feature Summary

• Dual independent output channels with 4A peak current drive capability
• Simultaneous inverting and non-inverting input configurations
• Integrated enable pin for precise power state control
• Robust design supporting low-side N-channel MOSFET switching

Gate Driver Applications

• Industrial motor control systems
• Power supply converter stages
• Battery management system interfaces
• General-purpose low-side switching applications

Gate Driver Procurement Notes

Verify the specific suffix PG4 indicates lead-free compliance status relative to standard UCC27425 variants. Confirm that the PDIP package matches the required through-hole mounting constraints for the target PCB layout. Ensure the operating voltage range aligns with the system's logic levels and gate drive requirements before finalizing procurement.

Gate Driver Selection Notes

Select this component when dual isolated low-side driving is required with moderate current demands. The presence of both inverted and non-inverted outputs simplifies bridge driver topologies without external phase-splitting components. Consider the PDIP package size if automated surface-mount assembly is not available or if manual prototyping is preferred for the specific application board.

Gate Driver Part Context

This part belongs to Texas Instruments' UCC27xxx series of high-speed gate drivers. It serves as a discrete solution for controlling power switches in medium-power conversion circuits. The device complements higher-current variants like the UCC2751x series by offering a compact, cost-effective option for lower power density designs requiring dual channel independence.

Gate Driver Replacement Considerations

The UCC27425DR is a tape-and-reel variant of the same functional device. Direct substitution requires verifying package compatibility between PDIP and SOIC formats. Other family members may offer different current ratings or voltage ranges but lack the identical dual-channel configuration.
