Description VNH2SP30 is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high side driver and two low side switches. The high side driver switch is designed using the STMicroelectronic’s well known and proven proprietary VIPower M0 technology which permits efficient integration on the same die of a true Power MOSFET with an intelligent signal/protection circuitary. The VIN and motor out are pitched for 5mm screw terminals, making it easy to connect larger gauge wires. INA and INB control the direction of each motor, and the PWM pins turns the motors on or off.

For the VNH2SP30, the current sense (CS) pins will output approximately 0.13 volts per amp of output current. Features. Voltage Range: 5.5V - 16V.

Maximum Current rating: 30A. Practical Continuous Current: 14 A. Current sense output proportional to motor current. MOSFET on-resistance: 19 mΩ (per leg). Maximum PWM frequency: 20 kHz. Thermal Shutdown. Undervoltage and Overvoltage shutdown.

This is the result of this tutorial: i. When user enter number '2', dc motor start to rotate forward and serial monitor will print forward. When user enter '3', dc motor start to reverse and serial monitor will print reverse.

When user enter '1', dc motor stop from rotating and serial monitor will print stop. When user enter '+', dc motor's speed increase by 10 and serial monitor will print the motor's speed. However, dc motor maximum speed is 255, thus, when user enter ' more it will still print 255 and never more than 255 (as shown in the pic). When user enter '-', dc motor's speed decrease by 10 and serial monitor will print the motor's speed.

However, dc motor minimum speed is 0, thus, when user enter '-' more it will still print 0 and never less than 0 (as shown in the pic). NevzatT, the solid state part that implements the switch on this board has a very low series resistance (0.019 ohms when in the 'on' state). This should allow you to predict how much voltage drop you would get from your high current application. Just multiply the current you are using by 0.019 and you will have the voltage drop. Be aware that the 30 amp rating of this switch is actually for peak, short duration, current flow like a starting current transient in a motor. If you were to run 30 amps continuously, you would cause about 17 watts of power to be dissipated in the switch, which would cause it to overheat and die given the amount of heat sinking is built into this little board.

The VNH3SP30-E is a full-bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver (HSD) and two low-side switches. The HSD switch is designed using STMicroelectronics proprietary VIPower™ M0-3 technology that efficiently integrates a true Power MOSFET with an intelligent signal/protection circuit on the same die. The low-side switches are vertical MOSFETs manufactured using STMicroelectronics proprietary EHD (“STripFET™”) process.

The three circuits are assembled in a MultiPowerSO-30 package on electrically isolated lead frames. This package, specifically designed for the harsh automotive environment, offers improved thermal performance thanks to exposed die pads. Moreover, its fully symmetrical mechanical design provides superior manufacturability at board level. The input signals IN A and IN B can directly interface with the microcontroller to select the motor direction and the brake condition.

Pins DIAG A/EN A or DIAG B/EN B, when connected to an external pull-up resistor, enable one leg of the bridge. They also provide a feedback digital diagnostic signal. The normal operating conditions are explained in the truth table. The speed of the motor can be controlled in all possible conditions by the PWM up to kHz.
