FlexSPIN™ Multi-Motor Programmable Drivers

Highly integrated for cost-driven applications such as printers. Controls and drives multi-motor applications (stepper and DC simultaneously) or inverter stages with its 4 fully-configurable full-bridge drivers.

FlexSPIN: SPI configurable stepper and DC multi motor driver

STM FlexSPIN Motor Driver

ST's FlexSPIN motor driver controls and powers multi-motor systems, through simultaneous management of stepper and DC motors. A number of features can be configured through the digital interface (SPI), including 3 voltage regulators, 1 high-precision ADC, 2 operational amplifiers and 14 configurable GPIOs. The highly-flexible L6460 may be configured as two half bridges or one full bridge to work as a power stage featuring additional voltage buck regulators.

Key benefits of FlexSPIN:

  • Optimization of motion-control system costs and space by using a single driver for multiple motors
  • Design flexibility: 4 configurable drivers to support different types of motor
  • Easily programmable through SPI interface
