9.3.6.2.1 Channel On

When a channel on, benefiting from the high-accuracy current sense in a small current range, if an open-load event occurs, it can be detected as an ultralow VCS and handled by the microcontroller. Note that the detection is not reported on the STx or FAULT pins. The microcontroller must multiplex the SEL and SEH pins to detect the channel-on open-load fault proactively.
