1. The circuit provides less than 1 V on the LVG and HVG pins (@ Isink = 10 mA), with VCC > 3 V. This allows
to omitting the “bleeder” resistor connected between the gate and the source of the external MOSFET
normally used to hold the pin low; the gate driver assures low impedance also in SD condition.
