MHP-TA Metal Hybrid PPTC Devices

Littelfuse MHP-TA devices help provide resettable over-temperature protection

Image of TE Connectivity's MHP-TA Metal Hybrid PPTC DevicesLittelfuse 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.

Benefits Applications
  • 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
    • E-readers
