Product details

What the 2.5A and 33V ratings mean for your motor-drive BOM

The DRV8424PPWPR is a fully integrated motor driver from Texas Instruments that combines control logic and a Power MOSFET output stage in one 28-PowerTSSOP package. It drives one bipolar stepper motor or two brushed DC motors using a PWM interface, with each half-bridge rated for 2.5A continuous output and a load supply range of 4.5V to 33V. That 33V ceiling comfortably covers 24V nominal industrial rails with margin for transients, while the 2.5A per-channel rating supports medium-torque stepper applications and small brushed motors in consumer and industrial equipment.

Package and thermal: 28-PowerTSSOP with exposed pad

The PowerTSSOP footprint is shared with other TI motor drivers in this family, so a layout designed for one can often accept the other with minor routing adjustments.

Frequently asked questions

Can DRV8424PPWPR drive a 24V stepper motor at 2A?

Yes. The load supply range goes up to 33V, so a 24V rail is well within spec, and the 2.5A per-channel output rating provides headroom above a 2A stepper winding current. Ensure the thermal pad is properly sinked to handle continuous 2A dissipation.

Can DRV8424PPWPR drive two brushed DC motors?

Yes. The output configuration is two half-bridges, which can independently drive two brushed DC motors using PWM control. Each half-bridge is rated for 2.5A.

What is a suitable replacement for DRV8424PPWPR?

The DRV8811PWPR is a related bipolar stepper driver from TI, but it uses a logic interface (not PWM), has a 1.9A output rating, and a different package — it is not a direct pin-compatible replacement. For a PWM-controlled drop-in, stay within the DRV8424 family or verify pin compatibility with the 28-PowerTSSOP footprint.
