This unipolar stepper motor driver circuit is used to drive a 12V unipolar stepper motor with a current rating of 1.25A. It uses PCA9537 IC, which is a 10-pin CMOS device that provides 4 bits of ...

ROHM Co., Ltd. has developed two new motor driver ICs for brushed DC motors, BD60210FV (20V, 2ch) and BD64950EFJ (40V, 1ch), which are intended for use in home and office appliances such as ...

Different types of motors need different types of drivers. Requirements for a variety of applications. Selecting the right motor driver is crucial to achieving the required functionality and ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...

Starting on Monday, September 19, and running through September 23, Design News will present the free course, DC Motor Controls with the RP2040 Pico. Each class runs an hour, beginning at 2:00 Eastern ...

Printed-circuit-board (PCB) substrate material, like FR-4 glass epoxy, is a poor conductor of heat. Conversely, copper is an excellent conductor of heat. So, more copper area on a PCB is ideal from a ...

This one is a bit dated, but the lessons are still relevant. [Zach Hoeken] posted about the challenges he faced building a CNC stepper driver. He was experimenting with Toshiba motor drivers back in ...

• The inductance in a stepper-motor phase winding limits how fast current rises when power is applied. • Series-resistor current limiting needs higher voltages for faster step rates, but higher ...
