Bipolar Stepper Motor Drivers

ROHM's stepping motor drivers provide users with design flexibility

Image of ROHM Semiconductor's Bipolar Stepping Motor DriversROHM's bipolar, pin-compatible stepping motor drivers provide users with both cost savings and design flexibility. Instead of using the highest rated part to cover all applications when users can accept a lower current solution, they can select a more economical part. Higher current ratings are often available when required and within the same series, they are package and pin compatible. This can provide an alternative when a motor supplier increases the current capability of a motor or a supplier change occurs and the replacement motor requires more current than the one it replaced. The same applies simply if more horsepower is required in a new design.

ROHM's stepping motor driver series includes standard, microstep, low- and high-voltage families with CLK-IN (clock input) or PARA-IN (parallel input) control. For drivers with the CLK-IN feature, a built-in translator allows IC control using a clock signal, which simplifies system design by reducing the number of port connections to an MCU and PC board traces.

Features
  • Single 5.5 V, 28 V, 42 V (max.) supply voltage (internal voltage regulator)
  • DMOS output (P-channel + N-channel)
  • Io (max): 2.0 A
  • Constant current PWM driver
  • Serial/CLK-IN with built-in translator
  • No charge pump required
  • Mixed decay mode
  • Linearly variable fast/slow decay ratio
  • Integrated 4-bit DAC
  • Ghost supply prevention
