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
: 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.
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.
Power voltage:
High output current:
High noise margin
