Datasheet Stepping Motor Driver series Micro step 36V Stepping Motor Drivers BD63510AEFV General Description Major Characteristics BD63510AEFV series are stepping motor drivers of Range of power supply voltage 8 28 V 1/16 micro step(sixteenth step) drive. As for its basic Rated output current 1.0 A function, it is a low power consumption bipolar PWM Rated output current (peak) 1.5 A constant current-drive driver with power supply rated Range of operating temperature -25+85 voltage of 36V and rated output current (DC) of 1.0A. Output ON resistance (total of upper 1.75 (Typ.) The input interface is CLK-IN type. and lower resistors) There are step modes of Full step & Half step, Quarter step, Sixteenth step mode by internal DAC (D-A Package W(Typ.) x D(Typ.)x H(Max.) converter), and for current decay mode, the ratio of HTSSOP-B28 9.70mm x 6.40mm x 1.00mm FAST DECAY & SLOW DECAY can be freely set, so the optimum control conditions for every motor can be realized. In addition, being able to drive with one system of power supply makes contribution to the set designs getting easy. Features 1) Single power supply input (rated voltage of 36V) 2) Rated output current:(DC) 1.0A 3) Low ON resistance DMOS output 4) CLK-IN drive mode 5) PWM constant current control (other oscillation) 6) Built-in spike noise cancel function (external noise filter is unnecessary) Basic application circuit 7) Full step, Half step, Quarter step, Sixteenth step drive GND 9 8) Timing free for changing step modes 9) Current decay mode switching function (linearly 15 CLK 14 PS variable FAST/SLOW DECAY ratio) CW CCW 16 10) Normal rotation & reverse rotation switching 18 MODE0 function MODE1 19 11) Power save function 20 ENABLE 11 12) Built-in logic input pull-down resistor TEST0 13) Power-on reset function VCC1 7 14) Thermal shutdown circuit (TSD) VREF 13 OUT1A 15) Over current protection circuit (OCP) 5 16) Under voltage lock out circuit (UVLO) 2 OUT1B 17) Over voltage lock out circuit (OVLO) 3 RNF1 18) Ghost Supply Prevention (protects against 4 malfunction when power supply is disconnected) RNF1S 19) Adjacent pins short protection VCC2 22 20) Inverted mounting protection OUT2A 21) Microminiature, ultra-thin and high heat-radiation CR 24 10 (exposed metal type) HTSSOP-B28 package 27 OUT2B 26 RNF2 Application MTH 12 25 PPC, multi-function printer, laser beam printer, and RNF2S TEST1 ink-jet printer 17 GND 1 Monitoring camera and WEB camera Sewing machine Photo printer, FAX, scanner and mini printer Figure 1.
