650 V high-side and low-side driver with integrated bootstrap diode
capacitor. The integrated diode with its resistance helps save cost and improve reliability by reducing external
components as shown below figures 12 and 13.

Standard bootstrap gate driver
The low ohmic current limiting resistor provides essential advantages over other competitor devices with high
ohmic bootstrap structures. A low ohmic resistor such as in the 2ED2110S06M family allows faster recharching of
the bootstrap capacitor during periods of small duty cycles on the low side transistor. The bootstrap diode is
usable for all kind power electronic converters. The bootstrap diode is a real pn-diode and is temperature robust.
It can be used at high temperatures with a low duty cycle of the low side transistor.
The bootstrap diode of the 2ED2110S06M family works with all control algorithms of modern power electronics,
such as trapezoidal or sinusoidal motor drives control.

Calculating the bootstrap capacitance CBS
Bootstrapping is a common method of pumping charges from a low potential to a higher one. With this technique
a supply voltage for the floating high side sections of the gate drive can be easily established according to Figure
14. This method has the advantage of being simple and low cost but may force some limitations on duty-cycle
and on-time since they are limited by the requirement to refresh the charge in the bootstrap capacitor. Proper
capacitor choice can reduce drastically these limitations.
