Simplify creating smaller, safer battery-powered devices with longer battery life

Littelfuse has introduced MHP–TAC Series Resettable Over-temperature Protection Devices, the latest addition to its line of battery mini-breakers. These devices connect a PPTC device in parallel with a bimetal protector (a resettable thermal cut-off device) to protect the high-capacity LiP and prismatic battery cells employed in consumer electronics and mobile devices from damage caused by overheating and overcurrents. Typical applications for devices include LiP and prismatic battery cells designed for use in battery-powered devices such as ultra-books, notebook PCs, smartphones, tablets and e-cigarettes. “At just 4.75mm x 2.8mm x 0.8mm, the MHP-TAC Series is the smallest overtemperature protection device available for lithium-ion battery cells used in today’s mobile devices and consumer electronics,” said Amy Chu, product manager, Electronics Business Unit at Littelfuse. “Not only can it help our battery manufacturer customers save valuable design space and weight, but it helps their products meet today’s heightened battery safety requirements.”
