Abstract: An electrical assembly includes a controller, a voltage tracker component, a clamp protection circuit, a plurality of analog inputs, and a plurality of pullups. The voltage tracker component may be electrically coupled to a battery. The clamp protection circuit may be electrically coupled between the voltage tracker component and the plurality of analog inputs. The plurality of pullups may be electrically coupled between the plurality of analog inputs and the clamp protection circuit. The clamp protection circuit may control power to the plurality of pullups and may provide a low impedance drain path for a short-circuit current from at least one analog input of the plurality of analog inputs.
