Procurement Notes
Verify the specific suffix E2 against the official ROHM datasheet to confirm compliance with environmental standards and pinout compatibility. Ensure the ordering quantity aligns with the manufacturer's reel packaging requirements. Cross-reference the part number with authorized distributors to confirm current availability and production lifecycle status before finalizing procurement plans.
Selection Notes
Select this component when a compact solution for single-phase BLDC motors is required. The VSON-10 package suits space-constrained designs. Verify that the load voltage does not exceed 18 V and that the thermal environment remains within the specified -40°C to +105°C range. Confirm that the system logic levels are compatible with the PWM interface inputs.
