Product description
The motor driver is an H-bridge for brushed DC motors. The VNH2SP30 chip comes from automotive electronics and is designed for high currents and demanding conditions. The direction of rotation is controlled via the INA and INB inputs, while the speed can be controlled using PWM up to 20 kHz.
A key feature is current monitoring via the CS pin, which provides an analog signal proportional to the motor load. The EN pin reports faults if the chip shuts down due to overheating or other failure conditions occur. With sufficient cooling, the module can handle 14 A continuously; peak loads of up to 30 A are possible for short periods. Without an additional heatsink, the current must be significantly lower because the maximum case temperature is 150 °C.
The module is typically used in robots and vehicles with high drive currents, where monitoring current consumption is also useful. Control connections are made via a 7-pin pin header, while the motor and power supply are connected to separate solder pads designed for thick cables. A DC motor, a power supply of up to 16 V, and a microcontroller or development board with a PWM output and digital inputs and outputs are required.
Safety information
The motor driver is intended exclusively for building prototypes and for testing and development purposes. In the event of overheating or a short circuit, the chip and circuit board may become very hot; adequate heat dissipation is required for continuous operation. Work on or near electrical installations is reserved for qualified electricians; if you are unsure about the power supply or sizing, consult a qualified electrician before commissioning.
