Semiconductor General Purpose 24 Volt Motor Drivers Slide 13

The LV873x is a good motor driver choice for textile and vending machines. With design goals such as low power, safety, and easy PCB layout, this is the part to choose. For low power, the DMOS process enables it to use less than 1 µA of current during standby and the low RON of the FET also dissipates less power than a power transistor would. Safety functions such as thermal shut down, over-current protection, and under-voltage lock out are incorporated. To facilitate an easy PCB layout for the designer, the same package and pin outs are used for different current rated parts. This enables the designer to easily put a higher or lower power driver in the same socket as motor requirements change. The micro stepping capability of this part not only enables more precise positioning, but also makes for a more smooth movement of the motor.
