PPTC circuit-protection devices are used to protect against harmful over current surges and over-temperature faults. Like traditional fuses, these limit the flow of dangerously high current during fault conditions. The PPTC device, however, automatically resets after the fault is cleared and power to the circuit is removed. Understanding the precise nature of these devices can help designers develop more reliable equipment and reduce warranty, service and repair costs. Improvements in size, cost and performance have resulted in wide spread ....etc

Circuit protection for rechargeable lithium-based battery cells and packs is a critical design consideration. Overcurrent and overtemperature conditions that can result from accidental shorting or abusive/runaway charging can raise temperatures high enough to damage components and cause substantial equipment damage.
Early circuit-protection designs relied on fragile one-shot fuses to provide total current interruption for overcurrent protection. However, because the majority of f ....etc
