EVAL6208Q

Stepper motor driver mounting the L6208Q

Data brief

Features■ Voltage range from 8 V to 52 V

■ Phase current up to 2.5 Ar.m.s.

■ Adjustable PWM current control OFF-time

■ Logic inputs 5 V / 3.3 V compliant

■ Small application footprint with high thermal performance

■ Suitable for use in combination with PractiSPIN™ 2 software

DescriptionThe EVAL6208Q is a stepper motor driver board allowing the user to test the L6208Q functions.

The board can be driven using the STEVAL-PCC009V2 communication board and the PractiSPIN 2 evaluation software.
