HIC (AC power input) 5-Phase Stepping Motor Drive IC for Universal Controller PMM8714PT Outline "PMM8714PT" is a Bi-CMOS monolithic IC to be used for controlling 5-phase stepping motor. This IC has been developed for the purpose to further simplify the usage of 5-phase stepping motor. When combined only with the switching elements or a power hybrid IC, this IC can configure a driver device for a 5-phase stepping motor. Characteristics • Universal controller : Selection is possible from the following three different excitation modes. • Power voltage: • High output current: • High noise margin • two kinds of pulse input • Power-down functions • Reset functions • Excitation mode preservation functions • Phase origin monitor • Determination monitor for excitation status • Input pulse monitor 4EX/4-5EX/5EX : Vcc=4V~16V : 20mA min(source) : Schmitt trigger circuit is integrated for the all input terminals : double input system (CW, CCW input mode), single input system (CK,U/D input mode) : Makes all the output to "L" level. : Shifts excitation status to the phase origin. : Phase output does not change even when excitation mode is switched as follows: 4EX_4-5EX_5EX. : Outputs at the "H" level at the time of phase origin (the output in reset mode). : Outputs monitor signal for the status of controller. : Outputs monitor signal for Vcc input pulse.
