Abstract:
A sensor integrated circuit includes an energy storage device having a first terminal coupled to a functional circuit and a blocking circuit coupled between a power supply pin and the first terminal of the energy storage device. The blocking circuit permits the energy storage device to store energy from an external power supply coupled to the power pin. The first terminal of the energy storage device is inaccessible from outside of the sensor IC. Additional features of the sensor IC can include a high regulator, a low regulator, and a low power circuit.
