Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2817DBVT is determined by the following critical parameters:

• Driven Configuration: Low-Side operation
• Channel Type: Single channel
• Package / Case: SC-74A, SOT-753 (SOT-23-5 footprint)
• Input Type: Non-Inverting
• Gate Type Compatibility: N-Channel MOSFET or IGBT
• Supply Voltage Range: Minimum 4V operation required
• Peak Output Current: Minimum 2A source and sink capability
• Operating Temperature Range: Minimum -40°C to 125°C

The UCC27519DBVR qualifies as a direct substitute based on these parameters. It maintains identical package geometry, driven configuration, channel type, and input polarity. The substitute part exceeds the original specifications in supply voltage range (4.5V ~ 18V), peak output current (4A, 4A), and operating temperature range (-40°C ~ 140°C), ensuring compatibility with existing designs while providing enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

The UCC27519DBVR is qualified as a direct substitute for the TPS2817DBVT based on electrical and mechanical compatibility. Both devices are manufactured by Texas Instruments, share identical package geometry (SOT-23-5), and maintain the same driven configuration and input polarity.

The substitute part holds Active product status, ensuring long-term availability and supply continuity compared to the Last Time Buy status of the original part. Both devices maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent applications.

The UCC27519DBVR provides enhanced performance specifications across all critical parameters: extended supply voltage range (4.5V ~ 18V versus 4V ~ 14V), increased peak output current capability (4A versus 2A), and faster switching characteristics (8ns/7ns rise/fall time versus 14ns/14ns). These improvements ensure the substitute part operates within design margins while maintaining backward compatibility with existing circuit implementations.

Frequently Asked Questions (FAQ)

Q: Can the UCC27519DBVR be used as a direct replacement for the TPS2817DBVT in existing designs?

A: Yes. Both devices share identical package geometry (SOT-23-5), driven configuration (low-side), channel type (single), and input polarity (non-inverting). The substitute part meets or exceeds all electrical specifications of the original part, ensuring functional compatibility in existing circuit layouts.

Q: What are the key differences between these two gate drivers?

A: The UCC27519DBVR provides enhanced specifications: supply voltage range extends to 18V (versus 14V maximum), peak output current increases to 4A (versus 2A), switching speed improves to 8ns/7ns (versus 14ns), and operating temperature range extends to 140°C (versus 125°C). The substitute part also supports IGBT gate driving in addition to N-Channel MOSFETs.

Q: Are there any PCB layout considerations when substituting these parts?

A: No layout modifications are required. Both devices use identical SC-74A, SOT-753 package geometry with the same pinout and footprint. Existing PCB designs require no changes for component substitution.

Q: What is the significance of the product status difference?

A: The TPS2817DBVT is classified as Last Time Buy, indicating limited future availability. The UCC27519DBVR maintains Active status, ensuring continued production and supply availability for long-term design support and volume requirements.

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

A: Yes. Both the TPS2817DBVT and UCC27519DBVR are ROHS3 compliant, REACH Unaffected, and carry identical moisture sensitivity levels (MSL 1, Unlimited). No compliance differences exist between the two parts.

Q: Can the UCC27519DBVR handle higher gate drive currents than the original part?

A: Yes. The substitute part delivers 4A peak output current for both source and sink configurations, compared to 2A for the TPS2817DBVT. This increased current capability allows driving larger or multiple gate capacitances with reduced switching times.
