Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPS2812P is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side only
• Channel Type: Synchronous dual-channel architecture
• Gate Type: N-Channel MOSFET driving capability
• Input Logic: Non-Inverting signal interpretation
• Voltage Supply Range: 4V ~ 14V minimum requirement
• Logic Thresholds: VIL = 1V, VIH = 4V
• Peak Output Current: 2A source and 2A sink capability
• Switching Performance: Rise/Fall times of 14ns/15ns
• Operating Temperature Range: -40°C ~ 125°C
• Regulatory Compliance: ROHS3 and REACH status

The TPS2812PWR qualifies as a direct functional equivalent, maintaining identical electrical specifications while differing only in packaging format and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The TPS2812PWR serves as the recommended substitute for the TPS2812P based on the following engineering criteria:

Electrical Equivalence: All functional parameters—supply voltage range, logic thresholds, output current ratings, and switching characteristics—are identical between the two parts. This ensures drop-in functional compatibility at the circuit level.

Regulatory Compliance: Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements without modification.

Product Lifecycle: The TPS2812PWR carries Active product status, ensuring long-term availability and continued manufacturer support. This addresses the Last Time Buy status of the TPS2812P.

Package Considerations: The primary difference lies in packaging format. The TPS2812P uses through-hole 8-DIP packaging, while the TPS2812PWR employs surface-mount 8-TSSOP packaging. PCB layout and assembly process modifications are required to accommodate this transition. The TPS2812PWR offers reduced board footprint and improved thermal characteristics typical of surface-mount technology.

Supply Chain: The TPS2812PWR demonstrates higher current inventory levels (8866 Pcs vs. 3589 Pcs), supporting improved supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TPS2812PWR directly replace the TPS2812P without circuit modifications?

A: Electrical functionality is identical, enabling direct signal-level substitution. However, PCB layout modifications are mandatory due to package format differences (through-hole DIP vs. surface-mount TSSOP). Footprint redesign and assembly process changes are required.

Q: Are there any performance differences between these parts?

A: No. Both parts share identical electrical specifications including supply voltage range (4V–14V), output current (2A source/sink), logic thresholds (1V/4V), and switching times (14ns/15ns rise, 15ns fall). Performance in gate-driving applications is equivalent.

Q: What is the significance of the different packaging formats?

A: The TPS2812P uses through-hole 8-DIP packaging suitable for breadboard prototyping and manual assembly. The TPS2812PWR uses surface-mount 8-TSSOP packaging, enabling automated assembly, reduced PCB area, and improved thermal performance. Selection depends on manufacturing capability and design requirements.

Q: Why is the TPS2812P marked as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued this product line. The TPS2812PWR, with Active status, represents the current manufacturing offering and ensures future availability for new designs and production runs.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across -40°C to 125°C (TA), meeting identical thermal specifications for industrial and automotive applications.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant and REACH unaffected, satisfying environmental regulations for EU and global markets without additional certification requirements.
