| 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.
