Methods and systems for low voltage detection in seat peripheral devices for transportation vehicles

A method of detecting a low voltage condition at a seat peripheral device for a transportation vehicle using a seat peripheral component coupled to a passenger seat, the seat peripheral component comprising a comparison component, a reference component, a processor electrically coupled to the comparison component, the method comprising:

• generating, by the reference component, a reference voltage associated with a power supply component of the transportation vehicle based on a supply voltage supplied to the seat peripheral device when a direct current (DC) voltage provided by the power supply component is at or above a threshold level, wherein the supply voltage is supplied to the seat peripheral device via a cable connected to the power supply component configured to provide the DC voltage to the cable;
• maintaining, by the reference component, the reference voltage at a same level as the reference voltage prior to a power interruption to prevent a premature reboot or a premature reinitialization of the seat peripheral device when the DC voltage drops below the threshold level to cause the supply voltage to drop during the power interruption;
• providing, by the reference component, the reference voltage to the comparison component;
• comparing, by the comparison component, an input voltage and the reference voltage, wherein the input voltage is based on the supply voltage;
• outputting, by the comparison component, a first output voltage in response to the input voltage exceeding the reference voltage, to the processor to indicate no power interruption at the power supply component;
• and
• outputting, by the comparison component, a second output voltage in response to the input voltage being less than or equal to the reference voltage, to the processor to indicate the power interruption at the power supply component.
