| HIC (AC power input) Universal Controller IC for the 2-Phase Stepping Motor Drive PMM8713PT 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 * * * * Source voltage High output current High noise margin 2 types of pulse input : The following 3 types of energization mode can be selected by switching at the energization mode switching terminal 1EX / 1-2EX / 2EX : Vcc=4.5~5.5V : 24mA min (sink, source) : Schmitt trigger circuit is incorporated for the all input terminals. : 2 input mode (CW, CCW input mode) 1 input mode (CK, U/D input mode) : Outputs the monitor signal of the controller status. * Excited status verification monitor Maximum Rating (Ta=25C) Item Source voltage Output current on Output current CO,EM Input voltage Input current Operating current Conservation temperature "H" level "L" level "H" level "L" level Symbol VCC IOH o IOL o IOH A IOL VIN IIN Topr -0.3~VCC+0.3 10 -20~85 Tstg V mA C -40~125 C Rating -0.3~7 -35 mA 35 Unit V Recommended Operating Conditions (Ta=20~85C) Rating Item Source voltage Output current "H" level on "L" level Symbol VCC IOH o IOL o IOH IOL VIN Min. 4.5 -24 24 -2 2 0 Standard - - - - - - Max. 5.5 - mA - - mA CO,EM,ZO Input voltage "L" level - VCC V Output current "H" level Unit V 103 Dimensions (Unit: mm) Pin No. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16.
