NOTE 2:
Care should be taken to avoid switching conditions where the VS node flies inductively below ground by more than 5V.
NOTE 3:
Enough current should be supplied to the VCC lead of the IC to keep the internal 15.6V zener diode clamping the
voltage at this lead.
Dynamic Electrical Characteristics
VBIAS (VCC, VBS) = 12V, TA = 25oC unless otherwise specified.
