The rapidly expanding market for ultra-thin portable electronic

devices, such as media tablets and ultra-thin PCs, has created

demand for very thin, low-profile, lightweight and high-capacity

Lithium Polymer (LiP) and prismatic cells.

A new MHP (Metal Hybrid PPTC) device, the MHP-TAM device,

offers a 9VDC rating and a higher current rating than typical battery

strap devices. This helps them meet the battery safety

requirements of higher-capacity LiP and prismatic batteries found

in the latest tablet and ultra-thin computing products. Hybrid MHP

technology connects a bimetal protector in parallel with a PPTC

(polymeric positive temperature coefficient) device. The resulting

MHP-TAM (Thermal Activation) series helps provide resettable

overtemperature and overcurrent protection, while utilizing the

PPTC device to act as a heater and to help keep the bimetal

latched until the fault is removed.
