• Applications needing precise micro-stepping resolution up to 1/32 step

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm exact electrical characteristics and packaging details. Ensure the application environment stays within the specified operating temperature range of -25°C to 85°C. Confirm that the load voltage does not exceed the 36V withstand limit. Check for any regional restrictions or automotive class limitations if used in vehicle-related contexts.

Selection Notes

Select this component when a low-power bipolar stepper driver with high voltage tolerance is required. It is suitable for designs needing fine micro-stepping capabilities without external complex circuitry. The integrated SPI interface allows for dynamic adjustment of drive parameters. Consider the VQFN040V6060 package size for PCB layout constraints. Ensure the system can accommodate the CLK-IN signal requirements for proper operation.

Part Context

This part belongs to ROHM Semiconductor's stepping motor driver series, designed for efficient motion control. It differs from general DC motor drivers by supporting specific bipolar PWM constant current control. The product is classified as standard grade and is not recommended for automotive use. It complements other motor controllers by offering detailed current decay optimization and multiple excitation modes.

Replacement Considerations

Check ROHM's official replacement list for updated versions. No direct public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing CLK-IN signals and SPI protocols before substituting with similar drivers from other manufacturers.
