HIC (AC power input) Universal Controller IC for the 2-Phase Stepping Motor Drive PMM8713PT Outline The universal controller “PMM8713PT” is the gate array IC (HIC) to control the 2-phase stepping motor drive. This product has been developed for the purpose to further simplify 2-phase stepping motor use, as combined only with switching elements or power hybrid ICs to configure a 2-phase stepping motor driver. Characteristics • Universal controller • • • • Source voltage High output current High noise margin 2 types of pulse input • Excited status verification monitor : The following 3 types of energization mode can be selected by switching at the energization mode switching terminal 1EX / 1-2EX / 2EX : Vcc=4.5~5.5V : 24mA min (sink, source) : Schmitt trigger circuit is incorporated for the all input terminals. : 2 input mode (CW, CCW input mode) 1 input mode (CK, U/D input mode) : Outputs the monitor signal of the controller status.
