Serialized as PolyZen CE series, the circuit protection device is just 1.0mm in hight, and operates at an industry-leading 2.6 ampheres, offering significant performance advantages over discrete solutions employing fuses, Zeners and other passive devices.
The high-integration also allows board designers to plug and play it into their systems, relieving them of painstakingly integrating and testing less effective discrete and most costly IC solutions.
As consumer electronics are increasingly sophisticated and jammed with a myriad of high voltage chips, system designers are strongly requiring robust circuit protection to help protect sensitive electronics from overvoltage and overcurrent charges.
Offered in a thin, compact package useful for space-constrained applications, the PolyZen CE series uses a thermally protected Zener diode to help protect electronics against voltage transients, reverse-bias and the incorrect use of power supplies.
The PolySwitch PPTC element shuts out excessive current while the fault condition remains and helps shield the Zener diode and downstream electronics from damage.
"When building circuit protection into tablets and other cutting-edge consumer products, manufacturers must weigh component costs against the high price of potential warranty returns that can ultimately compromise their brand," said Curtis Wong, Global Portfolio Product Manager for TE Circuit Protection.
"The two conventional approaches either provide inadequate protection or are less cost effective. Multiple discrete component solutions, such as fuses and TVS diodes, generally don't offer enough overvoltage protection, and ICs, with their unnecessary 'bells-and-whistles' features, are more costly. In contrast, our new PolyZen CE series hits the sweet spot of value-to-performance by offering a single placement, cost-effective solution that provides reliable, robust overvoltage and overcurrent protection for a wide variety of portable electronics applications."
The PolyZen CE series includes six devices with various current ratings to accommodate a wide range of applications. These include Tablet PCs and Ultrabooks, GPS and navigation systems, HDDs, SSDs, cell phone charger ports and USB power, portable media players and STBs, automotive infotainment power, DC power port, industrial handheld point-of-sale (POS) products.
