Input Voltage limit on VNH5050 Diag/ENA pin
Posted on August 14, 2014 at 03:20HiI'm designing a very compact quad VNH5050 12V Motor Driver board.I can optimize my design if I can pull-up the DIAG/ENA pins to 12V rather than the 5V Logic level.There is nothing else connected to these pins. Al...
Problem about L6482H (OCD failure)
Posted on August 22, 2014 at 19:45HiI have developed about motor control by using L6482H. I follow circuit form reference circuit of L6482H Eval board (same part). Now I stuck at OCD failure. I have construct a new board follow Eval board. In Eval b...
