voltage when output is off defines the under voltage protection operating voltage. Also sweeps the
BSU pin voltage from 6V to increase and change the HU pin voltage at 5 V→0 V→5 V each time. It
repeats similarly output is on. When the BSU pin voltage when output is on defines the under
voltage protection recovery voltage.
