STSPIN958 Scalable 5 A full-bridge driver for brushed DC motors

STMicroelectronics

The STSPIN958 is a 5A full bridge driver for brushed DC motors.

The power stage is designed with high dynamic performance, allowing to achieve high frequency PWM control with precise duty-cycle.

The device offers a current limiter with adjustable threshold and off-time with slow or mixed decay selection. Two amplifiers with fixed amplification factor are available for current sensing (using an external shunt resistor).

The adjustable slew-rate guarantees the best trade-off between performances and EMI.

Versatile power stage offers seven different ways of operation for a high level of flexibility.

The device offers a complete set of protection features including overcurrent, overtemperature and low bus voltage detection.
