Semiconductor General Purpose 24 Volt Motor Drivers Slide 17

The stepper motor and forward/reverse 24 V DC motor driver portfolio is quite broad. There are motor driver ICs available from the standard LSI division, Hybrid IC division, and from the HyperDevice division. The chart on this slide shows how they are segmented by current, voltage, and motor application type. For bipolar stepper motor drivers up to 2.5 A, the standard LSI division’s products are mainly used. This division also supports up to 4 A. If greater current is required, the HIC division has parts to support the application. Most of these stepper motor drivers are unipolar. DMOS refers to a process that uses FETs for the output. With the lower power consumption of the DMOS products comes higher current ratings than that produced on a bipolar process. For forward/reverse DC brush motor drivers, the System LSI products typically support up to 3 A, with 5 A supported depending on the use in the application. The HIC division can support up to 12 A. The Sanyo product offering for 24 V DC motor drivers is one of the largest in the industry with wide selection of current ratings.
