Littelfuse has introduced a series of MHP-TA metal hybrid PPTC devices to meet market needs. 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, light-weight and high-capacity Lithium Polymer (LiP) and prismatic cells.
The MHP-TA, a MHP (Metal Hybrid PPTC) device, offers a 9 VDC rating and a higher current rating than typical battery strap devices. It meets 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 bi-metal protector in parallel with a PPTC (polymeric positive temperature coefficient) device. The resulting MHP-TA device helps provide resettable overtemperature protection, while utilizing the PPTC device to act as a heater and to help keep the bimetal latched until the fault is removed.
- Capable of handling the higher voltages and battery discharge rates found in high-capacity LiP and prismatic cell applications.
- Provides resettable over-temperature protection in high-capacity LiP and prismatic cell applications.
- Battery cell protection for high-capacity Lithium Polymer and prismatic cells used in:
- Media tablets
- Ultra-thin notebook PCs
