Description
General part information
STSPIN948 Series
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).
