VNH2SP30 High Power Motor Driver - 14A

Part Number PROMR-008706 Category

This carrier board for ST s VNH2SP30 motor driver IC operates from 5.5 to 16 V and can deliver a continuous 14 A (30 A peak). It works with 5 V logic levels, supports ultrasonic (up to 20 kHz) PWM, and features current sense feedback (an analog voltage proportional to the motor current). Along with built-in protection against reverse-voltage, over-voltage, under-voltage, over-temperature, and over-current, these features make this product a great general-purpose motor driver.

This module is a compact breakout board for ST s high-power VNH2SP30 orVNH3SP30 motor driver IC, each of which is a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor. The basic operation of the driver is summarized below, but we also recommend careful reading of the VNH2SP30 datasheet (283k pdf) or VNH3SP30 datasheet (228k pdf) before using this product. The board incorporates most of the components of the typical application diagram on page 8 of the VNH2SP30 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. It ships fully populated with its SMD components, including the VNH2SP30 or VNHSP30 motor driver IC, as shown in the product picture.
