In summary, PolySwitch Strap Devices come in several material platforms to help protect battery applications. Each of these material platforms offers different performance characteristics, allowing the engineer greater design flexibility. They are suitable for current ratings from 1.1 A to 13 A  and voltage ratings from 6 V to 30 V. The devices assists in meeting regulatory requirements. The low resistance devices increase battery operating time and are ideal for Li-ion and Li-polymer battery packs.
