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.
4EX/4-5EX/5EX
• Power voltage:
: Vcc=4V~16V
• High output current:
: 20mA min(source)
• High noise margin
: Schmitt trigger circuit is integrated for the all input terminals
• two kinds of pulse input : double input system (CW, CCW input mode), single input system (CK,U/D input mode)
• Power-down functions : Makes all the output to "L" level.
• Reset functions
: Shifts excitation status to the phase origin.
• Excitation mode preservation functions : Phase output does not change even when excitation mode is switched as follows: 4EX_4-5EX_5EX.
• Phase origin monitor
: Outputs at the "H" level at the time of phase origin (the output in reset mode).
• Determination monitor for excitation status : Outputs monitor signal for the status of controller.
• Input pulse monitor
: Outputs monitor signal for Vcc input pulse.
