EVAL6206Q

EVAL6206Q Dual full bridge with programmable overcurrent Data brief AM11895v1 Features  Voltage range from 8 to 52 V  Phase current up to 2.5 Ar.m.s.  Adjustable overcurrent threshold  Logic inputs 5 V / 3.3 V compliant  Small application footprint with high thermal performance  Suitable for use in combination with PractiSPIN™ 2 software Description The EVAL6206Q demonstration board allows the user to test the L6206Q functions. The dual full bridges integrated into the L6206Q device can be used to drive a single 2-phase stepper motor or up to four DC motors (unidirectional). The bridges can also operate in parallel mode. The board can be driven using the STEVAL-PCC009V2 demonstration board and the PractiSPIN 2 evaluation software.
