Resolved! Using the L6474 when Reading the Status Byte with the GetParam(0x20 + 0x19) and GetStatus() or Command(0xD0) I get different results for the Status Byte.

To be honest the difference is 0x7F03 for the ReadParam() and 0xFF03 for the GetStatus()The documentation L6474Data Sheet (DoclD022529 Rev 4) says Bits 13, 14, and 15 should be 1 all the time. In one case Bit 15 is always 0 and the other case Bit 1...

If I dont use schottky or TVS diode between output of the IC and ground, do I damege the IC because of back emf voltage ? (VND5E160AJTR-E)

Hi all,I am using VND5E160AJTR-E for driving a inductive load. The values of inductive and resistive load is 15 mH and 12 ohm. As you know happening back emf pulse while driving a inductor load and I dont use schottky diode for cutting off back emf b...
