Circuit Protection Approach for High-Rate Discharge Li-Ion Battery Applications

摘要

In 2010, a metal hybrid PPTC (MHP) technology was introduced to address the rapidly expanding market for high-rate-discharge lithium ion (Li-Ion) battery applications. The MHP arc-less contact technology results in circuit protection devices capable of providing 30 A+ hold currents at voltage ratings over 30 VDC. The MHP devices offer designers a cost-effective, space-saving alternative to conventional battery pack design solutions. This article describes how the latest MHP technology, introduced in 2012, builds upon the previous-generation MHP device family by adding Smart Activation functionality.
