UCC27201AD

Overview

The UCC27201AD is a high-frequency half-bridge MOSFET gate driver manufactured by Texas Instruments. It features independent high-side and low-side outputs with a peak output current of 3 A. The device supports a bootstrap voltage up to 120 V and operates within a supply voltage range of 8 V to 17 V. Typical propagation delays are characterized by an 8 ns rise time and a 7 ns fall time. It functions in temperatures from -40°C to +140°C TJ and utilizes an 8-SOIC package.

Feature Summary

• Supports high-side switching with a 120 V bootstrap capability for driving N-channel power MOSFETs.
• Provides independent high-side and low-side channels with non-inverting logic inputs.
• Features negative voltage handling on the high-side output to withstand transient voltages during switching.

Applications

• High-frequency DC-DC converter topologies
• Industrial motor drive systems
• Power supply circuits requiring isolated or floating gate control

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm pinout compatibility and thermal pad configuration. Ensure the selected variant matches the required operating temperature range and packaging style for your PCB layout constraints.

Selection Notes

Select this component when designing circuits that require fast switching speeds and robust high-side drive capabilities. Consider the 3 A peak current rating for driving medium-power MOSFETs efficiently while maintaining low conduction losses in the driver stage.
