UCC27288DR

Overview

The UCC27288DR is a robust N-channel MOSFET gate driver from Texas Instruments, designed for half-bridge and synchronous buck topologies. It features a high-side/low-side configuration capable of driving two N-channel MOSFETs with a maximum switch node (HS) rating of 100V. The device delivers a peak sink current of 3.5A and a peak source current of 2.5A. Typical propagation delay is 16ns, with rise and fall times of 12ns and 10ns respectively under an 1800pF load. It operates within a supply voltage range of 8V to 16V and supports temperatures from -40°C to +150°C in an SOIC-8 package.

Feature Summary

• High-side and low-side configuration enables control of two N-channel MOSFETs in half-bridge or synchronous buck applications.
• Input pins and HS pin tolerate significant negative voltages, enhancing system robustness against transients.
• Independent inputs allow flexible control design, including the ability to overlap outputs via overlapping input signals.
• Integrated undervoltage lockout (UVLO) on both high-side and low-side drivers forces outputs low when VDD falls below thresholds.

Applications

• Half-bridge power converter circuits
• Synchronous buck DC-DC converter configurations
• Industrial motor drive systems

Procurement Notes

Verify the specific suffix DR indicates the SOIC-8 surface-mount package variant. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected component matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this driver for applications requiring independent high-side and low-side control with robust transient immunity. The wide operating temperature range and negative voltage tolerance make it suitable for harsh industrial environments. Verify that the external bootstrap diode selection aligns with the switching frequency and voltage requirements.
