UCC27289DR

Overview

The UCC27289DR is a half-bridge MOSFET gate driver from Texas Instruments, packaged in an SOIC-8 surface-mount format. It delivers a peak output current of 3.5 A and operates within a supply voltage range of 8 V to 16 V. The device features fast switching characteristics with a rise time of 12 ns and a fall time of 10 ns. It supports a wide operating temperature range from -40°C to +150°C. The component is designed for high-voltage applications, supporting bus voltages up to 120 V.

Feature Summary

• Provides robust half-bridge driving capability with high peak output current for efficient MOSFET switching.
• Engineered for high-voltage environments with support for bus voltages up to 120 V.
• Features fast propagation delays and low rise/fall times to minimize switching losses.
• Includes built-in protection mechanisms such as under-voltage lockout to ensure reliable operation.

Applications

• Industrial motor drives
• High-frequency power supplies
• Inverter circuits

Procurement Notes

Verify the specific suffix DR indicates tape-and-reel packaging when sourcing. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the 8 V to 16 V supply voltage range aligns with your system design. Check for RoHS compliance status if required by your manufacturing standards. Validate that the 150°C maximum junction temperature suits your thermal management strategy.

Selection Notes

Select this component for applications requiring high-speed switching and high-voltage tolerance. The 3.5 A drive strength is suitable for medium-power MOSFETs. Consider the SOIC-8 package for standard surface-mount assembly processes. Evaluate the 120 V rating against your specific bus voltage needs. Compare performance metrics with similar drivers if higher current or different packaging is required.

Part Context

The UCC27289 belongs to Texas Instruments' UCC2728x series of half-bridge gate drivers. This family focuses on providing reliable control for high-side and low-side MOSFETs in power conversion topologies. The DR suffix specifically denotes the reel-packaged version of the UCC2728D device, facilitating automated assembly.

Replacement Considerations

The UCC27284DRCR is a documented alternative within the same product family, offering similar half-bridge functionality. Verify pin compatibility and electrical specifications before substitution. Other members of the UCC2728x series may serve as replacements depending on specific drive current or package requirements.
