5-Phase Stepping Motor DriveIC for Universal Controller
PMM8714PT
\"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 combinedonly with the switching elements or a power hybrid IC, this IC can configure a driver device for a 5-phase steppingmotor.
• Universal controller• 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
: Selection is possible from the following three different excitation modes.
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.
