Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRV8425PPWPR are identified based on strict parametric equivalence within the following critical categories:

Matching Parameters (Substitution Basis):

• Manufacturer: Texas Instruments
• Category: Power Management (PMIC)
• Motor Type - Stepper: Bipolar
• Motor Type - AC, DC: Brushed DC
• Function: Driver - Fully Integrated, Control and Power Stage
• Output Configuration: Half Bridge (2)
• Interface: PWM
• Technology: Power MOSFET
• Voltage - Supply: 0V ~ 5.5V
• Voltage - Load: 4.5V ~ 33V
• Operating Temperature: -40°C ~ 125°C (TA)
• Package / Case: 28-PowerTSSOP (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Product Status: Active

Variable Parameter (Differentiator):

• Current - Output: 2A (main part) vs. 1.5A (substitute)

The DRV8426PPWPR qualifies as a parametric equivalent substitute with reduced output current specification. This substitution is valid for applications where the 1.5A output current rating meets system requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the DRV8425PPWPR and DRV8426PPWPR are active products from Texas Instruments with identical compliance certifications (RoHS Status: Not applicable; ECCN: EAR99; HTSUS: 8542.39.0001) and equivalent moisture sensitivity ratings.

Selection Criteria:

The DRV8425PPWPR is the primary selection for applications requiring 2A output current capacity. The DRV8426PPWPR serves as a substitute only when system design specifications permit operation at 1.5A output current.

Both devices share identical electrical operating ranges (supply voltage 0V ~ 5.5V, load voltage 4.5V ~ 33V, operating temperature -40°C ~ 125°C), identical package geometry (28-PowerTSSOP), and identical functional architecture (fully integrated bipolar stepper/brushed DC motor driver with PWM interface).

Component selection between these two parts depends exclusively on the maximum output current requirement of the target application. No other electrical or mechanical parameters differ between these devices.

Frequently Asked Questions (FAQ)

Q: Can the DRV8426PPWPR directly replace the DRV8425PPWPR in existing designs?

A: Direct replacement is possible only if the application's maximum motor current requirement does not exceed 1.5A. The DRV8426PPWPR has a reduced output current specification (1.5A vs. 2A). All other electrical and mechanical parameters are identical.

Q: Are the package dimensions identical between DRV8425PPWPR and DRV8426PPWPR?

A: Yes. Both devices use the 28-PowerTSSOP package with identical dimensions (0.173" width, 4.40mm). PCB layout and footprints are interchangeable.

Q: What is the primary difference between these two parts?

A: The sole parametric difference is output current rating. The DRV8425PPWPR supports 2A continuous output current, while the DRV8426PPWPR supports 1.5A continuous output current. All other specifications, including voltage ranges, temperature operating range, interface type, and motor compatibility, are identical.

Q: Do both parts support the same motor types?

A: Yes. Both the DRV8425PPWPR and DRV8426PPWPR support bipolar stepper motors and brushed DC motors with identical functional integration and control architecture.

Q: Are the supply and load voltage ranges identical?

A: Yes. Both devices operate with supply voltage 0V ~ 5.5V and load voltage 4.5V ~ 33V. Operating temperature range is identical at -40°C ~ 125°C.

Q: What is the moisture sensitivity level for both parts?

A: Both the DRV8425PPWPR and DRV8426PPWPR have Moisture Sensitivity Level (MSL) 3 with 168-hour floor life rating.
