STSPIN3P23TR

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

STSPIN3P2 integrates efficient and robust technologies from STMicroelectronics to provide reliable solutions at an unrivaled level for industrial applications. The level of protection offered by STSPIN3P2 is excellent, with a comprehensive set of features. The device is protected from overvoltage, undervoltage, overtemperature, and cross conduction. Furthermore, the design combines simplicity with advanced monitoring and optimized motor control.

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. In all cases, a low-level state on the PWM pin turns off both the LSA and LSB switches.

The STSPIN3P2 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.
