Product overview
Description
The STSPIN948 is a 4.5 A dual full-bridge driver for brushed DC motors or bipolar stepper motors.
The power stage is designed with high dynamic performance, allowing to achieve high frequency PWM control with precise duty-cycle.
Each full-bridge is totally independent with 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 several 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.
