Abstract

An open drain driver circuit includes an output terminal, an input terminal, a first transistor, a second transistor, and a third transistor. The first transistor includes a first terminal coupled to the output terminal, and a second terminal coupled to a reference voltage source. The second transistor includes a first terminal coupled to a third terminal of the first transistor, a second terminal coupled to a power supply rail, and a third terminal coupled to the reference voltage source. The third transistor includes a first terminal coupled to the input terminal, a second terminal coupled to the reference voltage source, and a third terminal coupled to the third terminal of the first transistor.
