HIC (AC power input)
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 * 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.

When VCC is not stable, such as immediately after the power is on, normal initial reset can not always be performed. In order to perform firm reset, hold R terminal (13pin) at the "L" level until Vcc becomes stable.
Vcc (24pin) 4V
R (13pin) 1.5V or lower OV
