and the source of the external mosfet normally used to hold the pin low; the gate driver

ensures low impedance also in SD conditions.

and lower than the turn on threshold. This allows to omit the bleeder resistor connected

between the gate and the source of the external mosfet normally used to hold the pin low;

the gate driver ensures low impedance also in SD conditions.

8

Vboot

Bootstrap Supply Voltage: it is the upper driver floating supply. The bootstrap capacitor

connected between this pin and pin 6 can be fed by an internal structure named ”bootstrap

driver” (a patented structure). This structure can replace the external bootstrap diode.
