Abstract
Systems and methods described herein provide a sensor integrated circuit (IC) having a high voltage bi-directional current source and disconnect switch that are configured to suppress undesirable voltage artifacts. The sensor IC can include a power pin for coupling to an external power supply, a reference pin, and a functional circuit. The bi-directional current source can be disposed in a current path between the power pin and an energy storage device and be configured to control a current flow to the energy storage device and a current flow from the energy storage device.
