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.
