TPS2814P Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TPS2814P is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-Channel MOSFETs in power management applications. This device features dual independent channels with inverting and non-inverting input configurations, operating across a 4V to 14V supply range. The TPS2814P is currently in Last Time Buy status, making identification of functionally equivalent alternatives essential for design continuity and long-term component sourcing strategy.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2814P is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Low-side gate driver configuration with dual independent channels
• Supply voltage range: minimum 4V, maximum 14V
• Dual input configuration supporting both inverting and non-inverting modes
• N-Channel MOSFET gate drive capability
• Operating temperature range: -40°C to 125°C

Mechanical Compatibility Criteria:

• Package type and pin count (8-pin configuration)
• Through-hole or surface-mount mounting compatibility with circuit board design

The UCC27425DR qualifies as a manufacturer-recommended substitute based on functional equivalence across these parameters, though with notable differences in output current capability and supply voltage ceiling.

Engineering Selection Recommendations

For Direct Replacement (Same Mounting Technology): The TPS2814P in through-hole 8-DIP packaging has no direct pin-compatible substitute listed. Designs requiring through-hole mounting must retain the TPS2814P or redesign the PCB layout to accommodate surface-mount alternatives.

For Surface-Mount Redesign: The UCC27425DR is the manufacturer-recommended substitute for applications where PCB redesign to surface-mount technology is feasible. This device is in Active product status, ensuring long-term availability and supply continuity. The UCC27425DR provides enhanced electrical performance with 4A peak output current (versus 2A) and extended supply voltage range to 15V, making it suitable for higher-power gate drive applications.

Compliance Considerations: Both devices maintain ROHS3 compliance and are classified under identical HTSUS and ECCN codes, supporting regulatory and export requirements equivalently.

Frequently Asked Questions (FAQ)

Q: Can the UCC27425DR directly replace the TPS2814P without PCB modification? A: No. The UCC27425DR uses 8-SOIC surface-mount packaging, while the TPS2814P uses 8-DIP through-hole packaging. PCB layout redesign is required to accommodate the different package form factor and pin spacing.

Q: What are the key electrical differences between these devices? A: The UCC27425DR provides higher peak output current (4A versus 2A), extended maximum supply voltage (15V versus 14V), and lower logic input threshold (VIH 2V versus 4V). These differences make the UCC27425DR suitable for higher-power applications but require verification of circuit compatibility.

Q: Why is the TPS2814P in Last Time Buy status? A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The UCC27425DR represents the active alternative for new designs and long-term sourcing.

Q: Are both devices RoHS compliant? A: Yes. Both the TPS2814P and UCC27425DR are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements.

Q: What is the primary substitution constraint? A: The primary constraint is packaging technology. The TPS2814P's through-hole 8-DIP package cannot be directly replaced by the surface-mount 8-SOIC UCC27425DR without circuit board redesign. Electrical parameters are compatible within the specified operating ranges.
