POLY-FUSE Resettable PTCs

Metal Hybrid PPTC > MHP Series

MHP-TAT18 Series Breaker

Description

The new Metal Hybrid PPTC device, MHP-TAT18, offers

a 9VDC rating and a higher current rating than typical

MHP-TAM device. This helps to meet the battery safety

requirements of higher-capacity LiP and prismatic

batteries found in the latest gaming PC and ultra-book

products. Hybrid MHP technology connects a bimetal

protector in parallel with a Polymeric PositiveTemperature

Coefﬁcient (PPTC) device. The resulting MHP-TAT18

(Thermal Activation) series helps to 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.

Features

Agency Approvals

• MiniatureThermal Cutoff (TCO) device

• High current capacity, low resistance

• Overtemperature and overcurrent protection

for lithium polymer and prismatic cells

• Multiple activation temperature ratings

(72°C, 77°C, 82°C, 85°C, 90°C)

Circuit Diagram

• Compact size (L: 5.8mm x W: 3.80mm x H: 1.05mm)

allows for ultra-thin battery pack designs

Applications

Battery cell protection for high-capacity Lithium Polymer

and Prismatic cells used in:

• Gaming PCs

• Notebook PCs

• Ultra-book

• Tablets

Precautions for Electrical Characteristics:

a. Device electrical characteristics may change depending on installation conditions. Users should independently evaluate the suitability of and test each product in their own application.

b. If any terminal or lead extensions are added to the device, especially in the case of high current discharging, the device performance may be negatively impacted due to variations

in welding methods or materials. Please avoid designs that might cause heat to be generated around the joints of the lead extensions or on the extended terminals.

c. SMT solder reﬂow, wave-soldering and manual soldering irons are not permitted.

Speciﬁcations are subject to change without notice.
