UCC27211D Equivalent & Substitute Parts

Part Overview

The UCC27211D is a half-bridge gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in half-bridge configurations. This device operates with a supply voltage range of 8V to 17V and delivers peak output currents of 4A for both source and sink operations. The UCC27211D is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent and substitute parts is necessary to ensure design continuity and maintain supply chain reliability for applications requiring half-bridge gate driver functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UCC27211D is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-bridge topology requirement
• Number of Drivers: Dual independent driver channels
• Gate Type: N-channel MOSFET gate drive capability
• Supply Voltage Range: 8V to 17V operation
• Peak Output Current: 4A source and sink capability
• Input Logic: Non-inverting input configuration
• Bootstrap Voltage Rating: 120V maximum high-side voltage
• Package Type: 8-SOIC surface mount form factor
• Electrical Timing: Rise and fall time specifications

The UCC27211DR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: UCC27211D is supplied in tube packaging, while UCC27211DR is supplied in cut tape and Digi-Reel format. Both parts share the same base product number (UCC27211) and are manufactured by Texas Instruments.

Parameter Comparison

Engineering Selection Recommendations

The UCC27211DR is a direct electrical and functional equivalent to the UCC27211D. Both parts are manufactured by Texas Instruments and share identical electrical specifications, logic thresholds, output drive capabilities, and thermal operating ranges. The parts are pin-compatible and functionally interchangeable at the circuit level.

The UCC27211D is designated Last Time Buy, indicating discontinued production. The UCC27211DR maintains Active product status with significantly higher inventory availability (75,200 pieces versus 3,600 pieces). Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1.

The primary consideration for part selection is packaging format. The UCC27211D is supplied in tube packaging, while the UCC27211DR is supplied in cut tape and Digi-Reel format. This distinction affects procurement logistics and automated assembly processes but does not impact electrical performance or circuit functionality.

Frequently Asked Questions (FAQ)

Q: Can UCC27211DR be used as a direct replacement for UCC27211D in existing designs?

A: Yes. The UCC27211DR is electrically and functionally identical to the UCC27211D. All electrical parameters, pin configurations, and performance characteristics are equivalent. The only difference is the packaging format (tube versus cut tape/Digi-Reel).

Q: What is the difference between tube and cut tape packaging?

A: Tube packaging supplies components in plastic tubes suitable for manual handling and small-volume assembly. Cut tape and Digi-Reel packaging supplies components on continuous tape suitable for automated pick-and-place assembly equipment. The electrical specifications and component quality are identical.

Q: Why is the UCC27211D marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory will be sold until depletion, after which the part will no longer be available. The UCC27211DR remains in active production and is the recommended alternative for new designs and ongoing supply requirements.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the UCC27211D and UCC27211DR maintain identical RoHS3 compliance, REACH unaffected status, and MSL rating of 1 (unlimited moisture sensitivity level). Regulatory and environmental compliance is equivalent.

Q: What are the critical parameters that define substitutability for half-bridge gate drivers?

A: Substitutability is determined by: driven configuration (half-bridge), number of independent driver channels (2), gate type (N-channel MOSFET), supply voltage range (8V to 17V), peak output current (4A source and sink), input logic type (non-inverting), bootstrap voltage rating (120V), package form factor (8-SOIC), and operating temperature range (-40°C to 140°C). All these parameters must match for functional equivalence.

Q: Can the UCC27211DR be used in high-volume automated assembly?

A: Yes. The UCC27211DR is supplied in cut tape and Digi-Reel format, which is optimized for automated pick-and-place assembly equipment. This packaging format is standard for high-volume manufacturing processes.
