† Care should be taken to avoid output switching conditions where the VS node flies inductively below
ground by more than 5 V.
†† Enough current should be supplied to the VCC pin to keep the internal 15.6 V zener diode clamping the
voltage at this pin.
††† Enough current should be supplied to the VBB pin to maintain a VBBSB voltage magnitude of VCLAMP1.
