HIC (DC power input)
HIC for 2-Phase Stepping Motor
PMM2301
Micro Step
Outline
The Stepping motor driver IC “PMM2301” is a power hybrid IC (HIC) packaging the integrated excitation mode
generation circuits and related switching elements for 2-phase stepping motor driving.
This product is developed for the purpose to further simplify 2-phase stepping motor use, as combined only with a few
peripheral parts to configure a 2-phase stepping motor driver.
Characteristics
• Sine wave driven micro-step driver.
• The current detection resistor is incorporated.
• MOSFET is used for the power driving circuit to reduce heating.
• Totally packaged to reduce parts for the peripheral circuit.
• Enables selection from the 5 various excitation modes by the external bit signal.

• Conditioned on the Mode 3=L, one pulse operation is performed at every rising and falling edge of the clock
pulse. Accordingly, the operation becomes unstable if the driving pulse duty ratio deviates from 50%.
