Patent ID: 8791727

Claim:
A low voltage isolation switch, comprising: first and second connection terminals; first and second voltage reference terminals; a driving block electrically coupled between the first and second voltage reference terminals and including: a first driving transistor electrically coupled between said first voltage reference terminal and a driving circuit node; and a second driving transistor electrically coupled between said driving circuit node and said second voltage reference terminal; an isolation block electrically coupled to the first and second connection terminals and to said driving circuit node, said isolation block including: a diode block electrically coupled between the first and second connection terminals; a control transistor electrically coupled across said diode block between said first and second connection terminals and having a control terminal electrically coupled to said driving circuit node; a voltage limiter block electrically coupled between the first connection terminal and the control terminal of the control transistor; and a resistor electrically coupling the isolation block to the driving circuit node.
