Stmicroelectronics L6470H L6470H Motor Driver Micro Stepping 3.3V to 5V Supply 45V/3A/2 Outputs HTSSOP-28

The L6470H is a fully integrated micro-stepping Motor Driver with motion engine and SPI. It is realized in analogue mixed signal technology, is an advanced fully integrated solution suitable for driving 2-phase bi-polar stepper motors with micro-stepping. dSPIN� Integrates a dual low RDS(ON)DMOS full bridge with all of the power switches equipped with an accurate on-chip current sensing circuitry suitable for non-dissipative current control and over-current protection. The digital control core can generate user defined motion profiles with acceleration, deceleration, speed or target position and easily programmed through a dedicated registers set. All commands and data registers including those used to set analogue values are sent through a standard 5Mbit/s SPI.

• Low RDS(ON)Power MOSFETs
• Programmable speed profile and positioning
• Programmable power MOS slew rate
• Up to 1/128 micro-stepping
• Sensorless stall detection
• SPI interface
• Low quiescent and standby currents
• Programmable non-dissipative over-current protection on high and low-side
• 2-level of over-temperature protection
