STSPIN948 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.
