VBO UVLO protection

Dedicated undervoltage protection is available on each bootstrap section between BOOTx and OUTx supply

pins. In order to avoid intermittent operation, a hysteresis sets the turn-off threshold with respect to the turn-on

threshold.

When VBO voltage goes below the VBOthOFF threshold, the HVG output of the corresponding bootstrap section is

switched off. When VBO voltage reaches the VBOthON threshold the device returns to normal operation and the

output remains off up to the next input pins transition that requests HVG to turn on.
