The DRV8818PWPR is a bipolar stepper motor driver from Texas Instruments, housed in a 28-pin HTSSOP package. It integrates an on-chip 1/8 microstepping indexer and supports Step/Dir control interfaces. The device delivers up to 2.5A output current with a supply voltage range of 8V to 35V. Logic operation is supported by a 3V to 5.5V VCC supply. It features programmable decay modes and PWM off-times, alongside internal protections for overcurrent, short circuit, undervoltage lockout, and overtemperature.
Verify the specific suffix 'PWP' or 'PWPR' against the datasheet to confirm the package type (HTSSOP) and reel quantity. Ensure the logic supply voltage requirements align with the system's 3V to 5.5V specification. Confirm RoHS compliance status if required by the manufacturing process. Check moisture sensitivity level handling procedures during assembly.
Select this component when a compact solution for bipolar stepper motors is required with integrated microstepping capabilities. It is suitable for applications needing precise motion control without external microstep controllers. Consider the thermal performance of the HTSSOP package relative to the expected load current and ambient temperature conditions.
This part belongs to the DRV8818 family of stepper motor drivers designed for space-constrained applications. It combines power MOSFETs with control logic in a single IC. The PWPR variant specifically denotes the tape and reel packaging option for automated surface-mount assembly processes.
Consult official substitution guides for equivalent devices within the DRV series. Verify pin compatibility and electrical specifications before replacing.
