Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. Test Circuit, V+ = VBOOST = 12V, VTSOURCE = 0V and Pins 1, 16 open. Gate
Feedback pins connected to Gate Drive pins unless otherwise specified.
