The apparatus may also include a control unit configured to receive the bitstream from the energy monitoring circuit, and modify a count value in response to a determined state of each bit of the bitstream. The control unit may also read a first value of the count value at a first time and at a later second time read a second value of the count value. The control unit may assert a wake-up signal in response to a determination that a difference between the first value and the second value is greater than a predetermined threshold value."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for a reduced current wake-up circuit for a battery management system","description":"An apparatus may include an energy monitoring circuit configured to generate a bitstream dependent upon an amount of charge passing through a sensing unit.
