CDOT DEVICE FOR WIRELESS CHARGING

A battery protection device includes a Charge/Discharge Over Temperature (CDOT) device and a wireless charging coil. The CDOT device consists of a first electrode, a second electrode, and a variable resistance material. The first electrode is located on a substrate and has a first collection of fingers. The second electrode is located on the substrate and has a second collection of fingers. The first fingers and the second fingers are disposed in an interdigitated, spaced-apart relationship with one another, resulting in a gap between them that is serpentine and tortuous. The variable resistance material changes its resistance in response to a change in temperature.
