It delivers 4A peak source and sink current with independent drive channels, enabling fast switching transitions and reduced dead-time losses. The supply range of 8V to 17V accommodates standard bias rails for industrial and telecom power supplies, while the bootstrap high-side voltage withstands up to 120V, covering 48V bus and 72V battery applications. ## Junction temperature rating and thermal design The 140°C TJ max allows headroom for self-heating at high switching frequencies, but the SOIC-8 thermal impedance (RθJA ~120°C/W with minimal copper) limits continuous power dissipation — a ground-plane thermal pad under the package is recommended for sustained high-frequency operation. ## Last Buy — sourcing window closing The UCC27211D is in Last Buy status per the manufacturer. This means the final purchase window is active but will close — no further production runs after the LTB date. Buyers should secure lifetime-buy quantities or qualify a pin-compatible alternative before inventory dries up.","metaTitle":"UCC27211D Half-Bridge Gate Driver, 4A Peak, 120V Bootstrap","metaDescription":"Texas Instruments UCC27211D half-bridge MOSFET driver. 4A peak source/sink, 120V bootstrap, 8V-17V supply, 8-SOIC.

The key difference is the enable logic polarity — the 'A' variant uses an active-high enable, while the 'D' variant uses an active-low enable (ENB). Verify the enable pin logic in your controller before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/UCC27211D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/UCC27211D when reusing this data.
