METHODS AND SYSTEMS FOR LOW VOLTAGE DETECTION IN SEAT PERIPHERAL DEVICES FOR TRANSPORTATION VEHICLES

Methods and systems are provided for a transportation vehicle. A seat peripheral device includes a comparison component, a reference component, and a processor. The comparison component is configured to compare an input voltage and a reference voltage associated with a power supply component, where the input voltage is based on a supply voltage supplied to the seat peripheral device via a cable connected to the power supply component providing a DC voltage, and to output an output voltage based on whether the input voltage exceeds the reference voltage. The reference component is configured to generate the reference voltage based on the supply voltage when the DC voltage is at or above a threshold level. When the DC voltage drops below the threshold level during the power interruption, the reference component is configured to maintain the reference voltage at a same level as the reference voltage prior the power interruption.
