DC Cigarette Lighters and Power Plug Adapters
Charger circuits for mobile phones, IPods, after-market hands free devices, or other
battery operated equipment use connectors to plug into automobile cigarette lighter
or power outlets. These assemblies must operate over a wide range of temperatures, charging conditions and in a harsh automotive environment. Typically, overcurrent protection, such as a PolySwitch PPTC device, and overvoltage protection are coordinated at the input to the charger to help meet the
stringent electrical requirement. A single PolyZen device can be used to help
protect against damage caused by overcurrent and overvoltage faults.
