TPS2829DBVT Equivalent & Substitute Parts

Part Overview

The TPS2829DBVT is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-Channel MOSFETs in power management applications. This device operates with a supply voltage range of 4V to 14V and delivers peak output currents of 2A for both source and sink configurations. The TPS2829DBVT is currently in Last Time Buy status, indicating that new production has ceased and existing inventory is limited. Finding equivalent substitute parts is necessary to ensure design continuity and long-term component availability for new designs or production runs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2829DBVT is determined by the following critical parameters:

• Driven Configuration: Must be Low-Side
• Channel Type: Must be Single channel
• Number of Drivers: Must be 1
• Input Type: Must be Non-Inverting
• Package / Case: Must be SC-74A or SOT-753 (SOT-23-5 footprint)
• Mounting Type: Must be Surface Mount
• Gate Type Compatibility: Must support N-Channel MOSFET (IGBT support is acceptable as an enhancement)
• Supply Voltage Range: Substitute must encompass or exceed the 4V ~ 14V range
• Peak Output Current: Substitute must meet or exceed 2A source and sink capability
• RoHS Compliance: Must maintain ROHS3 Compliant status

The UCC27519DBVR meets all substitution criteria and is classified as a manufacturer-recommended equivalent.

Parameter Comparison

Engineering Selection Recommendations

The UCC27519DBVR is the recommended substitute for the TPS2829DBVT based on the following engineering criteria:

Product Status & Availability: The TPS2829DBVT is in Last Time Buy status with limited inventory. The UCC27519DBVR is in Active production status with significantly higher inventory availability (17,244 pcs vs. 5,882 pcs), ensuring long-term supply chain continuity.

Compliance & Certifications: Both devices maintain ROHS3 Compliance, REACH Unaffected status, and identical ECCN and HTSUS classifications, ensuring regulatory equivalence for procurement and export purposes.

Functional Compatibility: The UCC27519DBVR maintains identical driven configuration (Low-Side), channel type (Single), number of drivers (1), input type (Non-Inverting), and package form factor (SC-74A, SOT-753). These parameters ensure direct functional substitution without circuit redesign.

Performance Enhancement: The UCC27519DBVR provides superior electrical performance with higher peak output current capability (4A vs. 2A), faster switching times (8ns/7ns vs. 14ns/14ns), and an extended supply voltage range (4.5V ~ 18V vs. 4V ~ 14V). These enhancements provide design margin and improved system efficiency without introducing compatibility issues.

Temperature Rating: The UCC27519DBVR supports an extended operating temperature range (-40°C ~ 140°C junction temperature vs. -40°C ~ 125°C ambient temperature), providing additional thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the UCC27519DBVR be used as a direct replacement for the TPS2829DBVT without circuit modifications?

A: Yes. Both devices share identical driven configuration (Low-Side), single-channel architecture, non-inverting input logic, and SC-74A/SOT-753 package footprint. No circuit modifications are required for functional substitution.

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

A: The UCC27519DBVR provides higher peak output current (4A vs. 2A), faster switching performance (8ns/7ns rise/fall time vs. 14ns/14ns), and an extended supply voltage range (4.5V ~ 18V vs. 4V ~ 14V). The UCC27519DBVR also supports both IGBT and N-Channel MOSFET gate driving, whereas the TPS2829DBVT is specified for N-Channel MOSFETs only.

Q: Are there any compatibility concerns with the extended supply voltage range of the UCC27519DBVR?

A: No. The UCC27519DBVR's extended supply voltage range (4.5V ~ 18V) encompasses the TPS2829DBVT operating range (4V ~ 14V). Designs operating within the original 4V ~ 14V specification will function identically. The minimum supply voltage for the UCC27519DBVR is 4.5V; designs requiring operation below 4.5V must verify compatibility with the original TPS2829DBVT specification.

Q: Does the faster switching time of the UCC27519DBVR affect circuit behavior?

A: The faster switching time (8ns/7ns vs. 14ns/14ns) represents an improvement that reduces gate drive delay and improves overall system efficiency. This does not introduce compatibility issues; however, designs with tight timing constraints should verify that the faster switching performance does not conflict with system-level timing requirements.

Q: Are both devices RoHS compliant?

A: Yes. Both the TPS2829DBVT and UCC27519DBVR are ROHS3 Compliant with identical REACH and ECCN classifications, ensuring regulatory equivalence for procurement and deployment.

Q: What is the inventory status for each device?

A: The TPS2829DBVT has 5,882 pcs in stock but is in Last Time Buy status, indicating production has ended. The UCC27519DBVR has 17,244 pcs in stock and is in Active production status, ensuring continued availability for future orders.
