VCC section
The L6585DE is supplied by applying voltage between the V
voltage lockout (UVLO) prevents the IC from operating with supply voltages too low to
guarantee the correct behavior of the internal structures.
An internal voltage clamp limits the voltage to around 17 V and can deliver up to 20 mA. For
this reason it cannot be used directly as a clamp for the charge pump (current peaks usually
reach several hundreds of mA), but can be easily used during startup in order to charge the
