STSPIN9P Series High-Current Motor Drives

STMicroelectronics motor drivers offer scalable, high-current solutions for brushed, stepper, and brushless DC motors

Image of STMicroelectronics STSPIN9P Series High-Current Motor DrivesThe STSPIN9P family from STMicroelectronics is a highly integrated and flexible series of motor drivers designed to support a wide range of low-voltage motors, including brushed DC, stepper, and brushless DC motors. With support for power ratings up to 500 W and a wide operating voltage range from 7 V to 75 V, the STSPIN9P series is ideal for industrial and consumer applications requiring high-current motor control.

The family includes both half-bridge (STSPIN9P1x) and full-bridge (STSPIN9P2x) topologies, offering pin-to-pin compatibility and scalability across different motor types and control strategies. Each device integrates low RDS(ON) MOSFETs (16 mΩ or 27 mΩ), reducing BOM size and improving thermal performance. Advanced features such as adjustable slew rate, an integrated current sensing amplifier, and embedded regulators make the STSPIN9P devices self-sufficient and efficient.

Protection features include undervoltage lockout (UVLO), overcurrent protection, thermal shutdown, and open-load detection. The integrated analog front end (AFE) with differential amplifier and comparator enables precise current control via PWM trimming or fixed off-time strategies. These features, combined with compact QFN packaging, make the STSPIN9P family a robust and versatile solution for motor control applications.
