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.

  • All features

    • Operating voltage up to 58 V
    • Maximum output current up to 4.5 Arms
    • Five driving methods with full-bridge and dual half-bridge parallel mode
    • RDS(ON) HS + LS = 0.36 Ω typ.
    • Adjustable power MOS slew rate
    • Integrated amplifiers with two different embedded current control techniques
    • Adjustable OFF-time with slow or mixed decay
    • Low consumption standby
    • Protections
      • UVLO
      • Overcurrent protection
      • Thermal shutdown
