PRODUCTION DATA
When a channel is on (ENx = High), benefiting from the high-accuracy current sense in a small current range, if an open-load event occurs, it can be detected as an ultra-low VCS and handled by the microcontroller. Note that the detection is not reported on the FAULT pin. The microcontroller must multiplex the SEL and SEH pins to detect the channel-on open-load fault proactively.
