  • Publication number: 20190327002
    Abstract: An example of an isolation sensor package is disclosed to include a first Integrated Circuit (IC) chip and a second IC chip. The first IC chip may include an input interface circuit that receives an input signal from a first input signal terminal and a second input signal terminal, where the input signal ranges between a first positive voltage and a first negative voltage. The first IC chip may further include a negative voltage generator that generates a second negative voltage, a level shifter that receives an output of the input interface circuit and generates a modified signal having a voltage level between a ground voltage provided to the ground terminal and a second positive voltage that is present at a voltage supply terminal. The first IC chip may further produce a signal based on the modified signal generated by the level shifter.
