Abstract
A voltage detector circuit including a ladder selector that includes a first node, a second node and a selector node. The voltage detector circuit also includes a first resistive ladder that includes a first string of resistors coupled between a sensing input node and the first node of the ladder selector and a first set of transistors. An input node of each transistor in the first set of transistors is coupled to a respective intermediate node between two resistors in a subset of resistors in the first string of resistors and an output node of each transistor in the first set of transistors is coupled to a sensing output node. The voltage detector circuit also includes a second resistive ladder that includes a second string of resistors coupled between the sensing input node and the second node of the ladder selector and a second set of transistors.
