INTEGRATED CIRCUIT DEVICE AND METHOD FOR DETECTING AN EXCESSIVE VOLTAGE STATE

摘要

An integrated circuit device (100) comprising at least one analogue to digital converter (ADC) (110). The at least one ADC (110) comprises at least one input (115) operably coupled to at least one external contact (105) of the integrated circuit device (100). The integrated circuit device (100) further comprises detection circuitry (120) comprising at least one detection module (130). The at least one detection module (130) being arranged to receive at a first input (132) thereof an indication (140) of a voltage level at the at least one input (115) of the at least one ADC (110), compare the received indication (140) to a threshold value (145), and if the received indication (140) exceeds the threshold value (145), output (135) an indication that an excessive voltage state at the at least one input (115) of the at least one ADC (110) has been detected.
