All rights reserved. 18.Apr.2013 Rev.002 www.rohm.com TSZ22111・15・001 BU24035GW ●Description of Blocks Stepping Motor Driver (1ch-4ch Driver) Built-in stepping motor driver of PWM driving type. Maximum 2 stepping motor can be driven independently. Built-in voltage feedback circuit of D-class type. 3ch/4ch drivers can also drive independently for DC motor or voice coil motor. (1) Control It corresponds to both Clock IN and Autonomous control. (ⅰ)Clock IN Control Set the registers for the stepping motor control. The stepping motor is rotated and synchronized with the input clock in the STATE pin. It is possible to select the mode of stepping motor control from μ-step, 1-2 phase excitation, 2 phase excitation and the number of edge for electrical angle cycle from 4, 8, 32, 64, 128, 256, 512 or 1024. (ⅱ)Autonomous Control The stepping motor is rotated by setting the registers for the stepping motor control. It is possible to select the mode of stepping motor control from μ-step (1024 portion), 1-2 phase excitation and 2 phase excitation. Cache Method Built-in Cache registers. Cache registers enable the setting of subsequent process while the motor is in operation. Through these registers, operations are done continuously. Up down method It is possible to set Up, Constant and Down operation before the motor is operates. SIN wave Control Logic PWM Control Logic SIF STM Control Logic H.B. H.B.
