UCC27289DRMR

Overview

The UCC27289DRMR is a half-bridge gate driver designed to drive two N-channel MOSFETs in high-side and low-side configurations. It operates with a supply voltage range of 8 V to 16 V and features an 8 V undervoltage lockout (UVLO). The device delivers a peak output current of 3.5 A, with typical rise and fall times of 12 ns and 10 ns, respectively. It functions within a temperature range of -40°C to +125°C and is housed in an 8-pin VSON package.

Feature Summary

• Drives two N-channel MOSFETs in high-side and low-side configurations
• Includes enable/disable functionality for power management
• Features 8 V undervoltage lockout protection

Applications

• High-side and low-side MOSFET switching
• Half-bridge converter topologies
• General-purpose NMOS driving

Procurement Notes

Verify the specific suffix DRMR corresponds to the VSON-8 package and reel packaging configuration. Confirm that the 8 V UVLO threshold and enable pin availability match the design requirements. Ensure thermal management aligns with the specified operating temperature range of -40°C to +125°C.

Selection Notes

Select this component when a compact half-bridge solution with integrated enable control is required. The VSON-8 package offers space efficiency compared to larger SOIC variants. Verify that the 3.5 A peak current capability meets the gate charge requirements of the target MOSFETs.

Part Context

This part belongs to the UCC27289 series of half-bridge drivers from Texas Instruments. It shares core electrical specifications with other variants like the UCC27289D but differs in package type. The DRMR suffix specifically denotes the VSON-8 footprint, distinguishing it from through-hole or standard surface-mount alternatives.

Replacement Considerations

UCC27289D serves as a functional equivalent with identical electrical characteristics but utilizes an SOIC-8 package instead of VSON-8.
