Integrated Circuits

This motor driver IC from ST operates from 5.5 to 24 V and can deliver a maximum of 30 A. For more information, please see the VNH5019A-E datasheet (475k pdf). We use this motor driver in our VNH5019 motor driver carrier and our dual VNH5019 motor driver shield for Arduino.

The VNH3SP30 is a great H-bridge motor driver for motors running from 6-16 V and drawing up to about 15 A. The chip is able to withstand 40-V transients, has a peak current of 30 A, and features various fault protection features such as over-temperature and over-current shutdown.

The VNH2SP30 is an improved version of the VNH3SP30 motor driver, featuring current sensing, increased drive capability, and a higher maximum PWM frequency of 20 kHz.

Note: This driver has been discontinued by ST. We recommend the newer and very similar VNH5019 as an alternative.
