UCC27211DDA Equivalent & Substitute Parts

Part Overview

The UCC27211DDA 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 UCC27211DDA is currently in Last Time Buy status, indicating that Texas Instruments has discontinued or will discontinue production. This status necessitates identifying equivalent substitute parts to ensure continued availability for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UCC27211DDA is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Half-Bridge topology must be maintained
• Number of Drivers: Exactly 2 independent drivers required
• Gate Type: N-Channel MOSFET driving capability
• Supply Voltage Range: 8V ~ 17V operation
• Peak Output Current: 4A source and 4A sink capability
• Input Logic: Non-Inverting input configuration
• Bootstrap Voltage Rating: 120V maximum high-side voltage
• Switching Performance: Rise and fall times of 7.2ns and 5.5ns respectively
• Package Compatibility: 8-PowerSOIC form factor with 0.154" (3.90mm) width
• Environmental Compliance: ROHS3 compliance and MSL Level 1 rating

The UCC27211DDAR is identified as the manufacturer-recommended substitute, maintaining identical electrical specifications and package form factor while differing only in packaging configuration (Cut Tape & Digi-Reel versus Tube).

Parameter Comparison

Engineering Selection Recommendations

The UCC27211DDAR is the direct substitute for the UCC27211DDA. Both devices are manufactured by Texas Instruments and share identical electrical and thermal specifications. The primary distinction is product status: the UCC27211DDA is designated Last Time Buy, while the UCC27211DDAR maintains Active status, ensuring continued availability and manufacturing support.

From a compliance perspective, both parts meet ROHS3 requirements and carry MSL Level 1 ratings, indicating no moisture sensitivity constraints during storage and handling. The REACH Unaffected status applies to both variants, confirming regulatory alignment for international applications.

The packaging difference between Tube (UCC27211DDA) and Cut Tape & Digi-Reel (UCC27211DDAR) does not affect electrical performance or PCB-level compatibility. Selection between these packaging options depends on procurement volume and assembly line requirements rather than technical functionality.

Frequently Asked Questions (FAQ)

Q: Can the UCC27211DDAR directly replace the UCC27211DDA in existing designs?

A: Yes. The UCC27211DDAR is electrically and mechanically identical to the UCC27211DDA. Both devices operate within the same supply voltage range (8V ~ 17V), deliver identical peak output currents (4A source/sink), and are packaged in the same 8-PowerSOIC form factor. No circuit modifications are required.

Q: Why is the UCC27211DDA marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has announced the end of production for this part number. Customers requiring this device should transition to the UCC27211DDAR, which maintains Active status and ensures long-term availability.

Q: What is the difference between Tube and Cut Tape & Digi-Reel packaging?

A: Tube packaging is used for lower-volume orders and manual assembly processes, while Cut Tape & Digi-Reel packaging is optimized for high-volume automated assembly. Both packaging formats contain identical components with no electrical differences. Selection depends on production volume and assembly equipment compatibility.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both the UCC27211DDA and UCC27211DDAR operate across the same temperature range (-40°C to 140°C junction temperature) and carry identical MSL Level 1 ratings. Environmental performance and reliability characteristics are equivalent.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both devices are ROHS3 compliant and REACH Unaffected. They carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring regulatory alignment for global applications.
