UCC3776N

Overview

The UCC3776N is a quad FET driver manufactured by Texas Instruments, designed for high-speed switching applications. It features four independent low-side drivers in a single package, providing robust gate drive capability for power MOSFETs or GaAs FETs. The device operates within a supply voltage range of 4.5V to 18V and supports peak output currents up to 2A per channel. It utilizes a PDIP-8 package for through-hole mounting, ensuring compatibility with standard PCB layouts. The component is rated for an operating temperature range from 0°C to +70°C, making it suitable for industrial environments requiring reliable signal amplification and isolation.

Feature Summary

• Integrates four independent low-side gate drivers for driving multiple power switches simultaneously
• Provides high peak output current capability to ensure fast switching transitions
• Supports wide supply voltage operation for flexibility in various power system designs

Applications

• Driving power MOSFETs in DC-DC converters
• Gate drive stages in motor control systems
• Switching applications for GaAs FETs in RF circuits

Procurement Notes

Verify the specific suffix 'N' confirms the PDIP-8 through-hole package variant. Confirm RoHS compliance status via the official datasheet as requirements vary by region. Ensure the supplier provides genuine Texas Instruments components to avoid counterfeit risks associated with high-demand driver ICs. Check for recent production lifecycle notices to confirm availability for long-term projects.

Selection Notes

Select this component when a compact solution for driving four low-side switches is required. It is appropriate for designs needing isolated or non-isolated gate drive signals with moderate current capabilities. Consider thermal management if multiple channels operate at high duty cycles. Compare against single-channel drivers if fewer outputs are needed to optimize board space and cost.

Part Context

The UCC3776 belongs to the UCC37xx series of FET drivers from Texas Instruments. This family focuses on providing efficient and reliable gate drive solutions for power electronics. The 'N' designation specifically identifies the plastic dual-in-line package version, distinguishing it from surface-mount variants like the DP or DCTR suffixes within the same functional family.

Replacement Considerations

The UCC1776 is listed as a similar part number with identical functional descriptions. Verify pinout compatibility and electrical specifications before substitution. Other quad drivers may require external level shifting or different supply configurations.
