The new Metal Hybrid PPTC device, MHP-TAC, offers higher voltage rating (12 V dc) and smaller size than typical MHP-TAM devices. MHP-TAC helps to meet the battery safety requirements of higher-capacity Li-ion polymer and prismatic batteries found in most mobile devices such as laptop PCs, tablets, and smart phones. MHP technology connects a bimetal protector in parallel with a Polymeric Positive Temperature Coefficient (PPTC) device. The PPTC device is to act as a heater and to help keep the bimetal latched until the fault is removed. The resulting MHP-TAC helps to provide resettable overtemperature protection. Miniature Thermal Cutoff (TCO) device High voltage rating Overtemperature and overcurrent protection for Lithium (Ion) Polymer and prismatic cells Multiple activation temperature ratings (72°C, 77°C, 82°C, 85°C, and 90°C) Compact size (4.75x2.x0.8 mm) allows for ultrathin battery pack designs
