Original question:
Tool/software:
Attaching the Motor drive schematic. When the circuits related to Q35, Q36, Q4, Q3 is removed we see Motor fault. But when populated it is working. we identified that there is register control for the VDS fault. So the register at address = 0x01h bits 0 & 1 via SPI. But when we are still seeing this fault. Can you suggest what could be issue? What can be done otherwise?
Hi,
Thank you for your questions.
When you remove FETs from GH1/GL1, need to avoid "Trying turn on GH1/GL1". SH1 should be HIZ always. Here is example for MODE=0. Otherwise DRV could detect some fault condtion.
