7.1
The floating high side driver may be supplied directly or by means of a bootstrap diode and capacitor. Either way, for a correct
power-up it is recommended to put at the pins VSH and VSL an electrolytic or tantalum capacitor and additionally a ceramic
capacitor of approximately 100 nF. The size of the electrolytic or tantalum capacitor depends on the gate capacitances of the
driven IGBT or MOSFET, the switching frequency and additional gate resistors and/or capacitors.
For a safe start-up with a bootstrap diode and capacitor it is recommended first to switch on the low-side IGBT. Thus, the
capacitor can be charged through the diode and provides sufficient gate voltage.

The pins GND and GNDL have to be connected externally through the shortest possible way. Thus, different ground refer-
ences result for different applications as shown for instance in Figure 11.
