The bootstrap diode (DBOOT) and supply capacitor (CBOOT) comprise the supply voltage for the high side driver
circuitry. To guarantee that the high-side supply is charged up before operation commences, the first pulse from the
output drivers comes from the LO pin. During under voltage lock-out mode, the high and low-side outputs are both
held low.
