Procurement Notes
Verify the specific ordering suffix DE8 against the manufacturer's official datasheet to ensure correct packaging and pin configuration. Confirm RoHS3 compliance status and MSL rating prior to assembly planning. Cross-reference the DigiKey part number 3565-RS8837YTDE8TR-ND for accurate distribution channel information and availability status.
Selection Notes
Select this component when designing circuits for bipolar stepper motors requiring a low-profile solution. Ensure the system voltage remains within the 2.5V to 7V supply range and that the load does not exceed 14V. Verify that the required output current of 1.8A aligns with the motor specifications and that the operating temperature range fits the application environment.
Part Context
This part belongs to the Runic Technology motor driver family, specifically optimized for camera applications. It integrates both the driver and power MOSFETs into a single small footprint, reducing board space compared to discrete solutions. The device is currently listed as active and available through major distributors like DigiKey.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult the manufacturer for direct equivalents or compatible alternatives with matching electrical parameters and pinout configurations.
