All rights reserved. 18.Mar.2014 Rev.001 www.rohm.com TSZ22111・14・001 Stepping Motor Driver series Micro step 36V Stepping Motor Drivers BD63510EFV ●General Description BD63510EFV series are stepping motor drivers of 1/16 micro step(sixteenth step) drive. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply rated voltage of 36V and rated output current (DC) of 1.0A. The input interface is CLK-IN type. There are step modes of Full step & Half step, Quarter step, Sixteenth step mode by internal DAC (D-A converter), and for current decay mode, the ratio of 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 design’s 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) 7) Full step, Half step, Quarter step, Sixteenth step drive 8) Timing free for changing step modes 9) Current decay mode switching function (linearly variable FAST/SLOW DECAY ratio) 10) Normal rotation & reverse rotation switching function 11) Power save function 12) Built-in logic input pull-down resistor 13) Power-on reset function 14) Thermal shutdown circuit (TSD) 15) Over current protection circuit (OCP) 16) Under voltage lock out circuit (UVLO) 17) Over voltage lock out circuit (OVLO) 18) Ghost Supply Prevention (protects against malfunction when power supply is disconnected) 19) Adjacent pins short protection 20) Inverted mounting protection 21) Microminiature, ultra-thin and high heat-radiation (exposed metal type) HTSSOP-B28 package ● Application ■ PPC, multi-function printer, laser beam printer, and ink-jet printer ■ Monitoring camera and WEB camera ■ Sewing machine ■ Photo printer, FAX, scanner and mini printer ■ Toy and robot ● Major Characteristics ■ Range of power supply voltage ■ Rated output current ■ Rated output current (peak) ■ Range of operating temperature ■ Output ON resistance (total of upper and lower resistors) 8～28 [V] 1.0 [A] 1.5 [A] -25～+85 [℃] 1.75 [Ω] (Typ.) ● Package W(Typ.) x D(Typ.)x H(Max.)
