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 :

The following 3 types of energization mode can be selected by switching at the energization mode switching terminal

1EX / 1-2EX / 2EX

• Source voltage : Vcc=4.5~5.5V

• High output current : 24mA min (sink, source)

• High noise margin : Schmitt trigger circuit is incorporated for the all input terminals.

• 2 types of pulse input :

2 input mode (CW, CCW input mode)

1 input mode (CK, U/D input mode)

• Excited status verification monitor : Outputs the monitor signal of the controller status.
