BTT6030-2ERA these two kinds of fault protection: 1. channel open (ON) state, the load is open circuit 2. output out pin short circuit to VBAT Please leave these two kinds of fault protection how to specifically go to do troubleshooting.

In both cases, the current through the high drive chip is very small, maybe slightly larger in case of an open circuit fault (consider that the output has a pull-down resistor, which creates a small current), but is the IS pin feedback current accuracy enough for such small currents to differentiate between the IS pins?

Hello.

The distinction of small currents does require high precision of the device as well as the MCU, so the external pull-up and pull-down resistors are usually used to differentiate between the two error conditions. For more details, please refer to my article: Infineon Technical Support Series|Open Circuit Detection for Intelligent High Side Switches

Also we are interested in your previous description of the device failure problem, so please help to add information about it in your previous post.
