TPS2819DBVT Equivalent & Substitute Parts

Part Overview

The TPS2819DBVT 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 TPS2819DBVT is currently in Last Time Buy status, indicating that the manufacturer has discontinued or will discontinue production. This status necessitates identifying functionally compatible substitute components to ensure design continuity and long-term supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2819DBVT is determined by the following critical parameters:

Functional Compatibility Criteria:

• Driven Configuration: Low-Side operation
• Channel Type: Single channel
• Input Type: Non-Inverting logic
• Package / Case: SC-74A, SOT-753 (SOT-23-5) for mechanical and electrical pin compatibility
• Gate Type: N-Channel MOSFET or IGBT compatibility

Electrical Performance Criteria:

• Supply Voltage Range: Must encompass or exceed the 4V to 14V operating window
• Peak Output Current: Must meet or exceed 2A source and sink requirements
• Logic Voltage Levels: Must be compatible with standard logic signal inputs
• Operating Temperature Range: Must support -40°C to 125°C minimum

Regulatory & Compliance Criteria:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level 1 (Unlimited)

The UCC27519DBVR qualifies as a direct substitute based on these parameters while offering enhanced electrical performance characteristics.

Engineering Selection Recommendations

TPS2819DBVT Status: Last Time Buy. This product status indicates manufacturer discontinuation. Existing inventory of 2200 pieces is available, but future procurement is not guaranteed. Design migration to an active product is recommended for new designs or long-term production requirements.

UCC27519DBVR Status: Active. This substitute maintains continuous manufacturing and supply availability. The UCC27519DBVR is ROHS3 compliant and REACH unaffected, meeting the same regulatory requirements as the TPS2819DBVT.

Selection Basis:

• Both devices share identical package geometry (SC-74A, SOT-753) and pin configuration, enabling direct PCB-level substitution without layout modifications.
• The UCC27519DBVR provides enhanced electrical performance with higher peak output current (4A vs. 2A) and faster switching times (8ns/7ns vs. 14ns/14ns), making it suitable for applications requiring improved drive capability.
• The UCC27519DBVR supports an extended supply voltage range (4.5V to 18V) and higher junction temperature rating (-40°C to 140°C), providing greater operational margin in demanding environments.
• Both devices maintain identical logic input type (Non-Inverting) and low-side gate driver configuration, ensuring functional compatibility in existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the UCC27519DBVR directly replace the TPS2819DBVT on the PCB?

A: Yes. Both devices use the SC-74A, SOT-753 (SOT-23-5) package with identical pin assignments. No PCB layout modifications are required for mechanical substitution. Electrical compatibility is maintained through matching low-side gate driver configuration and non-inverting input logic.

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

A: The UCC27519DBVR offers higher peak output current (4A vs. 2A), faster switching times (8ns/7ns vs. 14ns/14ns), extended supply voltage range (4.5V to 18V vs. 4V to 14V), and higher maximum junction temperature (140°C vs. 125°C). These enhancements provide improved performance headroom without compromising compatibility.

Q: Why is the TPS2819DBVT in Last Time Buy status?

A: Last Time Buy status indicates that Texas Instruments has discontinued or will discontinue production of this component. Customers are advised to transition to active alternatives for new designs and long-term supply chain continuity.

Q: Are there any logic voltage level differences I should consider?

A: The TPS2819DBVT specifies logic voltage levels (VIL = 1V, VIH = 4V). The UCC27519DBVR does not provide explicit logic voltage specifications in the available data. Both devices accept non-inverting logic inputs compatible with standard digital signal levels.

Q: What compliance certifications apply to both devices?

A: Both the TPS2819DBVT and UCC27519DBVR are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). These certifications ensure compatibility with modern manufacturing and environmental regulations.

Q: Can the UCC27519DBVR handle IGBT gate driving in addition to MOSFETs?

A: Yes. The UCC27519DBVR gate type specification includes both IGBT and N-Channel MOSFET compatibility, providing broader application flexibility compared to the TPS2819DBVT, which is specified for N-Channel MOSFETs only.
