FlexSPINSPI configurable multi-motor driver with micro-stepping from STMicroelectronics

 

FlexSPIN allows to power and control multi-motor systems, managing simultaneously stepper and DC motors, and providing a unique level of integration in term of control, power and additional features.

Through the serial peripheral interface bus (SPI), plenty of features can be configured, such as 3 voltage regulators, 1 high precision A/D converter, 2 operational amplifiers and 14 configurable GPIOS.

The possibility to drive simultaneously stepper and DC motors makes FlexSPIN the ideal solution for all the applications featuring multi-motors.

Features

  • Mixed-signal DMOS power technology
  • 13 to 40 V operating voltage
  • 4 full bridge driver configurable for:
  • 1 stepper motor and 2 DC motors
  • 4 DC motors
  • each bridge configurable as:
  • 2 independent half bridges, 1 super half bridge, 2 power switches
  • 3 to 5 embedded voltage regulators featuring a full power supply management
  • 16 bit SPI interface
  • Programmable watchdog function
  • Integrated power sequencing and supervisory functions with fault signaling through serial interface and external reset pin
  • Very low power dissipation in shut-down mode (35 mW)
  • Full set of diagnostic and protection functions embedded
  • Thermal shut-down and warning
  • Multi-channels 9 bit ADC
  • 2 operational amplifiers
  • Digital comparator
  • 2 low voltage power switches
  • 3 general purpose PWM generators
  • 14 GPIOs
  • TQFP64 exposed pad package

Key Products

  • Highly flexible L6460 that may be configured as two half bridges or one full bridge to work as a power stage featuring additional voltage buck regulators.
