STSPIN958TR [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.

• Operating voltage up to 58V
• Maximum output current up to 5 Arms
• Seven driving methods with dual half-bridge, single full-bridge and half-bridge parallel mode
• R_DS(ON) HS + LS = 0.33 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
