TPS2811PW Equivalent & Substitute Parts

Part Overview

The TPS2811PW is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-channel MOSFETs in synchronous configurations. This device operates with a supply voltage range of 4V to 14V and delivers peak output currents of 2A for both source and sink operations. The TPS2811PW is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary to ensure continued design support and procurement availability for new production runs and long-term system maintenance.

Substitute Part Grouping Explanation

Substitution of the TPS2811PW is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation only
• Number of Drivers: Exactly 2 channels
• Gate Type: N-Channel MOSFET driving capability
• Voltage - Supply: 4V ~ 14V range
• Current - Peak Output: 2A source and 2A sink capability
• Input Type: Inverting logic
• Package / Case: 8-TSSOP form factor
• Rise / Fall Time: 14ns rise, 15ns fall (typical)
• Operating Temperature Range: -40°C ~ 125°C

The TPS2811PWR qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary difference is packaging format: TPS2811PW is supplied in Tube packaging, while TPS2811PWR is supplied in Tape & Reel (TR) format. Both parts share the same base product number (TPS2811) and are manufactured by Texas Instruments.

Engineering Selection Recommendations

The TPS2811PWR is the recommended substitute for the TPS2811PW. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The TPS2811PWR maintains Active product status, ensuring continued availability and manufacturing support, whereas the TPS2811PW is in Last Time Buy status.

Selection between these parts should be based on procurement requirements:

• TPS2811PW (Tube packaging): Suitable for lower-volume applications or manual assembly processes where tube packaging is preferred.
• TPS2811PWR (Tape & Reel packaging): Suitable for high-volume production environments utilizing automated pick-and-place assembly equipment.

Both parts carry ROHS3 compliance and MSL Level 1 rating, meeting environmental and moisture sensitivity requirements. No functional or electrical differences exist between these variants.

Frequently Asked Questions (FAQ)

Q: Can TPS2811PWR be used as a direct replacement for TPS2811PW in existing designs?

A: Yes. The TPS2811PWR is electrically and mechanically identical to the TPS2811PW. The only difference is packaging format (Tape & Reel versus Tube). No circuit modifications or design changes are required.

Q: What is the primary reason for substitution?

A: The TPS2811PW is in Last Time Buy status, indicating end-of-life production. The TPS2811PWR maintains Active status and ensures long-term availability for continued production and support.

Q: Are there any compatibility concerns with automated assembly equipment?

A: No. Both parts use the same 8-TSSOP package. The TPS2811PWR in Tape & Reel format is optimized for automated pick-and-place assembly, while the TPS2811PW in Tube format is suitable for manual or lower-volume assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TPS2811PW and TPS2811PWR are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 rating. No compliance differences exist between the two variants.

Q: What are the critical electrical parameters that define substitution eligibility?

A: Substitution is determined by matching: low-side driven configuration, 2-channel driver count, N-channel MOSFET gate type, 4V to 14V supply voltage range, 2A peak output current (source and sink), inverting input logic, and -40°C to 125°C operating temperature range.
