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. The MXP which was the first product in the family operates in the 9-14 mΩ resistance range. Next, the MLP which is a low temperature variant acts as a thermal cut-off at lower temperatures and operates at 1.0 A at 70°C. Finally, there is the MGP which has a higher hold current of 1.6 A and is suitable for higher battery discharge rates. The devices are also offered in several different packages. MGPC provides a better withstand of pack assembly pressure and has a stable leakage current. It also features a oxygen barrier that eliminates coating. Weldable packages can be reflowed to PCB and the weld surface of the cell contacts. Finally cell top packages can be mounted onto the surface of the cell. This maximizes thermal coupling and provides a low installation cost and consistent assembly.
