Abstract
A connection detection circuit includes a first detection circuit and a second detection circuit. The first detection circuit includes a first comparator and a first detection pin connected to the first comparator. The first comparator is adapted to compare a first voltage level on the first detection pin with a first reference voltage. The second detection circuit includes a second detection pin. The second detection pin is adapted to connect to the first detection pin to vary the first voltage level on the first detection pin to switch an first transistor output when the connection of the first detection circuit and the second detection circuit is achieved.

A connection detection circuit, comprising:
- a first detection circuit comprising a first comparator and a first detection pin connected to the first comparator, the first comparator adapted to compare a first voltage level on the first detection pin with a first reference voltage;
- and
- a second detection circuit comprising a second detection pin;
- wherein the second detection pin is adapted to connect to the first detection pin to change the first voltage level on the first detection pin to vary a first comparator output when an connection of the first detection circuit and the second detection circuit is achieved.
A connection detection circuit comprising:
- a first detection circuit comprising a first detection pin;
- and
- a second detection circuit comprising a second detection pin and a switch connected to the second detection pin, the switch adapted to output a first indication signal when a connection of the first detection circuit and the second detection circuit is achieved, and adapted to send a second indication signal when there is no connection between the first detection circuit and the second detection circuit.
