HIC (DC power input) HIC for 5-Phase Stepping Motor PMM5301 PMM5303 Outline PMM530 is a single packaged power hybrid IC of the switching elements to be used for driving 5-phase stepping motor. This HIC has been developed for the purpose to further simplify the usage of 5-phase stepping motor. When combined only with the controller IC to generate the excitation mode, this HIC can configure a driver device for a 5-phase stepping motor. Characteristics • High speed and high torque rotation by 5-phase pentagon system. • Constant voltage and constant current PWM driving system (excited by others). • Power voltage (driving power) : VCC1=18~42V : 4A max. (1A/phase) • High output current • Reduced heat generation by using MOSFET for the power drive element. • The all-in-one packaging reduces number of parts around peripheral circuits. • Two package types are available, enabling flexible PCB designing.
