Product details

The parallel interface accepts simple step/direction or phase/enable signals from a microcontroller or motion controller, making it a straightforward drop-in for general-purpose motion control in printers, ATMs, robotics, and factory automation.

1.75 A per bridge — sizing the load budget

Each of the four half-bridges delivers 1.75 A continuous. That figure is the per-bridge current limit; the total package dissipation must be checked against the thermal impedance of the 28-HTSSOP pad. For a bipolar stepper winding at 1.75 A, the copper area on the PCB and any forced airflow determine whether the part stays within its 150°C junction limit.

The 150°C TJ ceiling is the silicon limit, not the board-level rating — the thermal pad of the 28-HTSSOP must be soldered to a sufficient copper pour to keep the die below that threshold under full load.

Frequently asked questions

What are the alternatives to DRV8813PWPR?

The closest functional alternative is the DRV8811PWPR. Both are fully integrated bipolar stepper/brushed DC drivers in the same 28-HTSSOP package with four half-bridges. The key difference is supply voltage: the DRV8813PWPR operates from 8.2 V to 45 V, while the DRV8811PWPR runs from a lower 3.0 V supply rail. If your design uses a 3.3 V or 5 V logic supply and a separate motor voltage, the DRV8811PWPR may be a better fit.

How to use DRV8813PWPR with a microcontroller?

The DRV8813PWPR accepts parallel logic inputs — typically step and direction for stepper control, or phase and enable for brushed DC. The interface is compatible with 3.3 V and 5 V logic families, so it can connect directly to GPIO pins on most microcontrollers or Arduino boards. No SPI or I2C configuration is needed; the bridge outputs are controlled by the logic states on the parallel pins.

Is DRV8813PWPR compatible with 3.3V logic?

Yes, the parallel logic inputs are compatible with 3.3 V logic levels. The input thresholds are specified for standard CMOS/TTL levels, so a 3.3 V microcontroller can drive the step, direction, and enable pins directly without level shifters.
