VNH2SP30 Motor Driver Carrier MD01B

CHF35.98

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. 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 or VNH3SP30 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. 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. (Note that the current sense circuit might not be populated on the VNH3SP30 version of the board since only the VNH2SP30 supports current sense.)

In a typical application, the motor power supply is connected at the bottom of the board, the motor on the right side of the board, and the control connections to the left side of the board. The diagnostic/enable pins are pulled high on the board and can be left disconnected if you do not want to monitor the fault conditions of the motor driver chip. INA and INB control the direction of the motor, and the PWM pin turns the motor outputs on or off, allowing you to control motor speed with a supplied pulse width modulation (PWM) signal. The PWM pin is pulled low on the board, so the motor driver outputs are effectively disabled by default; the INA and INB pins are floating (they are not pulled to any particular default voltage). See the truth tables in the VNH2SP30/VNH3SP30 datasheet for more information on how the INA, INB, and PWM pins affect the driver outputs, OUTA and OUTB.

Note: An 8-pin 0.1″ male header and two 2-pin terminal blocks are included but not soldered onto the boards. You can solder these in yourself and use this board with custom cables or solderless breadboards, or you can solder wires directly to the board for more compact installations.
