Integrated circuit device and method for detecting an excessive voltage state

摘要

An integrated circuit device comprising at least one analog to digital converter. The at least one ADC comprises at least one input operably coupled to at least one external contact of the integrated circuit device. The integrated circuit device further comprises detection circuitry comprising at least one detection module. The at least one detection module being arranged to receive at a first input thereof an indication of a voltage level at the at least one input of the at least one ADC, compare the received indication to a threshold value, and if the received indication exceeds the threshold value, output an indication that an excessive voltage state at the at least one input of the at least one ADC has been detected.

1. An integrated circuit device comprising at least one analogue to digital converter, the at least one ADC comprising at least one input operably coupled to at least one external contact of the integrated circuit device; wherein the integrated circuit device further comprises detection circuitry comprising at least one detection module arranged to:
receive at a first input thereof an indication of a voltage level at the at least one input of the at least one ADC; compare the received indication to a threshold value; and if the received indication exceeds the threshold value, output an indication that an excessive voltage state at the at least one input of the at least one ADC has been detected, wherein the indication that the excessive voltage state has been detected is utilized to prevent propagation of output values from the at least one ADC caused by the excessive voltage state.
