Abstract
Analog switch circuits, methods for use with analog switch circuits, and devices and systems including analog switch circuits are disclosed herein. Such analog switch circuits include an analog switch input terminal (In), an analog switch output terminal (Out), and an analog switch control terminal (Ctl). During a normal-voltage condition, the input terminal (In) of the analog switch circuit is selectively connected and disconnected to/from the output terminal (Out) in dependence on a control signal received at the control terminal (Ctl). During an over-voltage condition, the input terminal (In) is disconnected from the output terminal (Out) regardless of the control signal received at the control terminal (Ctl). Additionally, during an under-voltage condition, the input terminal (In) is disconnected from the output terminal (Out) regardless of the control signal received at the analog switch control terminal (Ctl). In specific embodiments, symmetric protection and/or power-off protection is/are also provided.
