DRV8424PRGER Equivalent & Substitute Parts

Part Overview

The DRV8424PRGER is an active, fully integrated bipolar stepper motor driver manufactured by Texas Instruments. This Power Management (PMIC) device integrates control and power stage functionality in a 24-VQFN (4x4) surface mount package. The device operates with a supply voltage range of 0V to 5.5V and supports load voltages from 4.5V to 33V, delivering 2.5A output current. The DRV8424PRGER is supplied in Tape & Reel (TR) packaging and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified based on matching electrical specifications, mechanical compatibility, and functional parameters. Substitutes may differ in interface control methodology, output current ratings, or packaging format while maintaining core operational compatibility within the same product family.

Substitute Part Grouping Explanation

Substitute parts for the DRV8424PRGER are identified within the Texas Instruments DRV8424 and DRV8425 product families based on the following substitution criteria:

Primary Substitution Criteria:

• 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)
• Technology: Power MOSFET
• Voltage - Supply: 0V ~ 5.5V
• Voltage - Load: 4.5V ~ 33V
• Operating Temperature: -40°C ~ 125°C (TA)
• Mounting Type: Surface Mount
• Package / Case: 24-VFQFN Exposed Pad
• Supplier Device Package: 24-VQFN (4x4)
• Product Status: Active

Variable Parameters Allowing Substitution:

• Interface: PWM (main part) versus Phase/Enable (PH/EN) (substitute parts)
• Current - Output: 2.5A (main part) versus 2.5A (DRV8424ERGER) or 2A (DRV8425ERGER)
• Packaging Format: Tape & Reel (TR) (main part) versus Cut Tape (CT) & Digi-Reel® (DRV8424ERGER) or Tape & Reel (TR) (DRV8425ERGER)

The DRV8424ERGER and DRV8425ERGER are parametric equivalents that maintain electrical and mechanical compatibility while offering alternative control interfaces and current ratings within the same package footprint.

Parameter Comparison

Engineering Selection Recommendations

DRV8424PRGER (Main Part) The DRV8424PRGER is the primary selection for applications requiring PWM interface control with 2.5A output current. This part is ROHS3 compliant and supplied in Tape & Reel (TR) packaging. The device is active and suitable for consumer and industrial applications requiring bipolar stepper or brushed DC motor control.

DRV8424ERGER (Parametric Equivalent) The DRV8424ERGER provides identical electrical specifications and current rating (2.5A) to the DRV8424PRGER but implements Phase/Enable (PH/EN) control interface instead of PWM. This part is ROHS3 compliant and supplied in Cut Tape (CT) & Digi-Reel® packaging. Selection of this substitute requires system-level compatibility with Phase/Enable control methodology and packaging format acceptance.

DRV8425ERGER (Parametric Equivalent) The DRV8425ERGER operates within the same voltage and temperature specifications but delivers 2A maximum output current (reduced from 2.5A) and implements Phase/Enable (PH/EN) control interface. This part is supplied in Tape & Reel (TR) packaging. RoHS status is not applicable for this variant. Selection of this substitute is appropriate for applications with output current requirements not exceeding 2A and requiring Phase/Enable control interface.

All three parts maintain identical mechanical compatibility with the 24-VQFN (4x4) surface mount package footprint and are manufactured by Texas Instruments with active product status.

Frequently Asked Questions (FAQ)

Q: Can DRV8424ERGER be used as a direct replacement for DRV8424PRGER?

A: The DRV8424ERGER is mechanically and electrically compatible with the DRV8424PRGER in terms of package footprint, voltage specifications, and current rating (2.5A). However, the control interface differs: DRV8424PRGER uses PWM control while DRV8424ERGER uses Phase/Enable (PH/EN) control. Direct substitution requires system-level compatibility with the Phase/Enable control methodology. Packaging format also differs: DRV8424PRGER is supplied in Tape & Reel (TR) while DRV8424ERGER is supplied in Cut Tape (CT) & Digi-Reel®.

Q: What is the difference between DRV8424ERGER and DRV8425ERGER?

A: Both parts implement Phase/Enable (PH/EN) control interface and share identical voltage specifications (0V ~ 5.5V supply, 4.5V ~ 33V load). The primary difference is output current rating: DRV8424ERGER delivers 2.5A while DRV8425ERGER delivers 2A. Both are supplied in Tape & Reel (TR) packaging. Selection between these parts depends on application current requirements. DRV8424ERGER is ROHS3 compliant; DRV8425ERGER RoHS status is not applicable.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts (DRV8424PRGER, DRV8424ERGER, and DRV8425ERGER) use the 24-VQFN (4x4) surface mount package with 24-VFQFN Exposed Pad case designation. PCB footprint compatibility is maintained across all three variants.

Q: What control interface differences exist between the substitute parts?

A: The DRV8424PRGER uses PWM (Pulse Width Modulation) control interface. Both DRV8424ERGER and DRV8425ERGER use Phase/Enable (PH/EN) control interface. These represent different control methodologies and require corresponding system-level implementation differences. PWM control modulates pulse width to regulate motor speed, while Phase/Enable control uses separate phase and enable signals.

Q: Which part should be selected for maximum output current capability?

A: Both DRV8424PRGER and DRV8424ERGER deliver 2.5A maximum output current. The DRV8425ERGER is rated for 2A maximum output current. For applications requiring 2.5A output current, either DRV8424PRGER or DRV8424ERGER is appropriate, with selection based on control interface requirements (PWM versus Phase/Enable).

Q: Are there compliance or regulatory differences between these parts?

A: DRV8424PRGER and DRV8424ERGER are both ROHS3 compliant. DRV8425ERGER RoHS status is not applicable. All three parts are REACH unaffected and classified under ECCN EAR99. All three parts have unlimited moisture sensitivity level (MSL 1). Compliance requirements should be verified against specific application and regional regulations.

Q: What packaging format options are available?

A: DRV8424PRGER is supplied in Tape & Reel (TR) packaging. DRV8424ERGER is supplied in Cut Tape (CT) & Digi-Reel® packaging. DRV8425ERGER is supplied in Tape & Reel (TR) packaging. Packaging format selection depends on assembly process requirements and component handling procedures.
