The DRV8818PWPR from Texas Instruments is an integrated stepper motor driver designed for applications such as printers, scanners, and textile machines. It features two H-bridge drivers and microstepping indexer logic, supporting resolutions up to 1/8 microstep.
This device operates within an 8V to 35V supply voltage range and offers a full-scale current of 2.5A per winding, with a peak output current of 3.5A. The low RDS(ON) of 370mΩ (HS + LS) at 25°C contributes to efficient operation. It includes a simple STEP/DIRECTION interface for easy control and programmable decay modes.
Protection features are built-in, including undervoltage lockout (UVLO), overcurrent protection (OCP), and thermal shutdown (TSD). The DRV8818PWPR is housed in a 28-HTSSOP package, suitable for surface mounting.
Key specifications include a wide operating temperature range of -40°C to 150°C (TJ), a low sleep current of 3µA, and mixed decay mode support. The device is pin-to-pin compatible with the DRV8811 and DRV8818A.
