Abstract
Systems and methods described herein a sensor integrated circuit (IC) is provided having a protection circuit configured to protect circuitry within the IC from a transient pulse on a connection (i.e., power pin) to a power supply that is configured to provide power to the IC. The protection circuit can be disposed in a current path between a power pin of the IC and additional circuitry or nodes within the IC, such as but not limited to, a regulator or a bi-directional current source. The protection circuit includes a reverse blocking device having a first terminal coupled to the power supply at which a predetermined power supply voltage is provided and a second terminal coupled to an input of the regulator.
