TPIC44L02DB Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TPIC44L02DB is a low-side gate driver IC manufactured by Texas Instruments, designed for driving N-Channel and P-Channel MOSFETs in independent channel configurations. This device operates with a supply voltage range of 4.5V to 5.5V and features non-inverting logic inputs with four independent driver channels in a 24-SSOP surface mount package.

The TPIC44L02DB is currently in Last Time Buy status, indicating end-of-life production. Identifying equivalent substitute parts is necessary for design continuity, long-term supply chain planning, and new production runs where active alternatives are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPIC44L02DB is determined by strict equivalence across the following critical parameters:

• Driven Configuration: Low-Side operation only
• Number of Drivers: Four independent channels
• Gate Type: Support for both N-Channel and P-Channel MOSFETs
• Supply Voltage Range: 4.5V to 5.5V
• Peak Output Current: 1.2mA source and sink capability
• Input Logic: Non-Inverting configuration
• Package: 24-SSOP surface mount form factor
• Rise/Fall Time Performance: 4.6µs rise, 3µs fall (typical)
• Operating Temperature Range: -40°C to 150°C (TJ)

The TPIC44L02DBR is the direct substitute, differing only in packaging format (Tape & Reel versus Tube) while maintaining identical electrical specifications and functional performance.

Parameter Comparison

Engineering Selection Recommendations

The TPIC44L02DBR is the manufacturer-recommended substitute for the TPIC44L02DB. Both parts are manufactured by Texas Instruments and share identical electrical and functional specifications. The distinction lies in product status and packaging format.

The TPIC44L02DB is designated Last Time Buy, indicating limited future availability. The TPIC44L02DBR maintains Active product status, ensuring continued supply and support from the manufacturer. Both parts carry ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

For new designs and production runs, the TPIC44L02DBR is the appropriate selection due to its active status and availability in Tape & Reel packaging, which is standard for automated assembly processes. The Tape & Reel format also provides cost advantages in high-volume manufacturing scenarios.

Frequently Asked Questions (FAQ)

Q: Can the TPIC44L02DBR directly replace the TPIC44L02DB in existing designs?

A: Yes. The TPIC44L02DBR is electrically and functionally identical to the TPIC44L02DB. Both devices operate with the same supply voltage range (4.5V to 5.5V), provide identical peak output current (1.2mA source and sink), and feature the same 24-SSOP package footprint. No circuit modifications are required.

Q: What is the difference between Tube and Tape & Reel packaging?

A: Tube packaging (TPIC44L02DB) is suitable for manual assembly and small-quantity orders. Tape & Reel packaging (TPIC44L02DBR) is designed for automated pick-and-place assembly equipment and is standard for high-volume production. Both formats contain the same die and provide identical electrical performance.

Q: Why is the TPIC44L02DB marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued active production of this part number. Existing inventory may be available, but no new manufacturing runs are planned. The TPIC44L02DBR remains in active production as the recommended alternative.

Q: Are there any compliance or certification differences between these parts?

A: No. Both the TPIC44L02DB and TPIC44L02DBR carry identical certifications: ROHS3 compliance, REACH unaffected status, and MSL Level 1 (unlimited moisture sensitivity). Both are suitable for applications requiring environmental and regulatory compliance.

Q: What is the recommended part for new production designs?

A: The TPIC44L02DBR is recommended for new designs. It maintains active product status, ensuring long-term availability and manufacturer support. The Tape & Reel packaging format is optimized for modern manufacturing processes.
