Littelfuse, the leading circuit protection firm on global level, recently came up with its latest product called MHP-TAT 18 Meta Hybrid PPTC Battery Mini-Breaker with a resettable Thermal Cut-Off (TCO). It is an advanced over-temperature protection equipment is capable of providing a 9VDC rating along with a higher current rating against other devices in similar entities in the same category. This new equipment would be of great help to circuit designers who need to meet battery safety prerequisites for higher-capacity prismatic battery cells and lithium ion polymer present in all present day battery powered products, portable consumer products.
MHP technology would help connecting a bimetal protector in parallel along with a PPTC (Polymeric Positive Temperature Coefficient) equipment, here PPTC works as a heater and aids in keeping the bimetal latched till fault is eliminated completely. Though its application ranges across several areas, the typical areas include gaming PCs, tablets, ultra-books, Notebook PCs, and so forth. According to the product manager of Electronics Business Unit from Littelfuse, Amy Chu, “Compared to similar protection devices on the market, MHP-TAT18 Metal Hybrid PPTC Mini-Breakers with thermal cut-off can handle higher currents in a smaller, thinner form factor. Their welding leads can also be customized to facilitate a customer’s design process.”
The list of benefits associated with MHP-TAT-18 Metal Hybrid PPTC Mini-Breaker Series with resettable TCO goes to quite an extent. Firstly, its low resistance and high current capacity allow it to handle the battery and voltage charges rates present in high-capacity lithium ion prismatic and polymer cells. Also, its multiple activation temperature ratings can help offering resettable and precise protections from over-temperature. Its compact form also helps in offering accurate protection to ultra-thin battery pack designs.
