“It is well suited for constant-current control stepper motor applications including those found in office automation, commercial and industrial equipment. It is also suited for surveillance cameras and projectors,” said Toshiba.
Named TB67S549FTG, its internal constant-current control does not require an external current sense resistor, and the internal charge pump includes its capacitor.
Also integrated is something Toshiba calls ‘advanced dynamic mixed decay that “guarantees efficient PWM current control under all conditions. Up to 32 micro steps can be realised”.
