Toshiba combines leading-edge and original technologies a with an advanced process to offer solutions to satisfy customers' needs and issues. An extensive line up of stepping motor driver ICs in a variety of specifications and package types support higher energy efficiency, reduced heat and improved reliability.
A 50V / 5A rated bipolar stepping motor driver that supports 1/128 microstepping. TB67S128FTG meets the often conflicting requirements of high speed, high performance and reduced power consumption making it ideal for a wide variety of applications where high accuracy and quiet operation are critical.
A dual channel high resolution micro-stepping motor driver IC that is capable of driving motors with a wide range of operating voltages. The IC can drive a 128 micro-stepping motor with a voltage ranging from 2.5 V to 16 V at currents up to 2 A. An ultra-low standby current of just 0.1 µA prolongs battery life and the ability to operate with a 1.8 V to 5.0 V interface allows connection to a wide variety of hosts and microcontrollers. As a result, the device is suited for use in USB powered and battery powered applications as well as with standard 9-12V system devices.
Toshiba's original ADMD technology tracks input current more closely than the conventional mixed-decay mode, making highly efficient motor control possible at high rpm.
Toshiba's original ACDS technology enables motor drive with highly accurate constant current without requiring external current-sensing resistors.
The reduced part count also helps reduce the board area and the bill-of-material (BOM) cost.
The step angle is 360 degrees divided by the total number of poles.
For the four poles, 360 degrees/4 = 90 degrees.
Assuming there is a 36-pole motor, 360 degrees/36 = 10 degrees, and the single-step operating angle of the full-step mode is 10 degrees.
One step angle of the half-step mode is 1/2 of the full-step mode.
One step angle of the micro-step mode can be selected to be 1/4 of the full-step mode and a finer step angle.
