AutoDriver - stepper motor driver

STMicro’s L6470 is a 3A, 8-45V bipolar stepper motor driver. It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function. As if that weren’t enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting.

Features:

• Supports up to 128 Microsteps per Full Step
• Over-Temperature Detect
• Over-Current Detect
• Under-Voltage Detect
• PWM Drive-Voltage Limiting
• SPI Controlled
• On-Board Oscillator and Speed/Location Registers
• Stall Detection
• 5-bit ADC
