DRV8706-Q1: Off Line Diagnostics

Tool/software:

Related to https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1249338/drv8874-unrush-current-trippling-fault-due-to-capacitance-of-circuit but I am using discrete gate driver and MOSFETs.

The H-bridge generates a differential signal that has data encoded on it and supplies power to downstream devices. Some devices have large reservoir capacitors that can initially look like a short circuit at switch on and cause a large in-rush current.

Could I use the off-line diagnostics current sources to pre-charge the capacitance (I realise at 3 mA it could take some time), or will the current source be disabled if a short is detected?
