Tle9862 controller shows overcurrent and shutdown bridge driver even there is no load.
We have custom board has followed all designing details
and if we disable this overcurrrent shutdown functionality it shows short circut on external fet with that motor start roatating.
So if there is any kind short circuit on fet then how motor is motor. So can guid where is problem exactly..

Hello Roshan,
could you please measure the VDH and SHx voltages and crosscheck if the OC is caused by transient events or constantly too high voltage levels?
