EVLSPIN3P23

The EVLSPIN3P2 demonstration board is a fully integrated H-bridge motor driver, which allows the evaluation of all the STSPIN3P2 features.

The board includes the minimum set of electrical components recommended in the device datasheet. This configuration allows the user to connect the load, power supply, and microcontroller directly, without additional external component design or connection.

The board can be stacked with an X-Nucleo MCU control board through Arduino® connectors or driven directly by external pins.

STSPIN3P2 is a full-bridge product series that expands the capability of STSPIN family for low-voltage DC motors.

The level of protection offered by STSPIN3P is excellent, with a comprehensive set of features. The device is protected from overvoltage, undervoltage, overtemperature, and cross conduction.

The STSPIN3P series is assembled in a QFN 6×6 mm triple-pad 26+2L package equipped with three exposed islands for optimized dissipation performance. This package is designed for harsh industrial environments and offers improved thermal performance due to exposed die pads.

The input signals INA and INB can interface directly with the microcontroller to select the motor direction and the brake condition. Two selection pins, SEL0 and SEL1, are available to access information on the MultiSense pin and PH_OUT pin.

The MultiSense pin enables monitoring the motor current by delivering a current proportional to the motor current value and provides the diagnostic feedback. The PH_OUT pin provides feedback on the OUT status, confirming that the motor operates correctly.

The PWM, with a frequency of up to 25 kHz, allows control of the motor speed under all conditions.
