Protection chip eliminates TVS diodes in USB-C designs
The KTU1108 features DPST switches on the CC 1 and 2 lines with low capacitance and low on-resistance for passing VCONN power up to 1.25A while providing a high bandwidth for communications. Dead battery pull-down protection is also included on the CC lines to ensure the up-stream power source provides 5V on VBUS. Key applications include laptop and desktop computers, and smartphones, tablets and wearables.
“Kinetic Technologies has developed the KTU1108 to increase USB Type-C port protection against a multitude of power fault conditions,” said Kinetic Technologies Vice President David Nam. “Our integrated ESD protection meets IEC61000-4-2 standards, and our ultra-fast (15ns typ.) OVP minimizes output voltage spikes. Compliance with IEC61000-4-5 increases immunity against nature-induced surges, like lightning strikes on power lines, while the KTU1108 also eliminates system damage due to physical- or moisture-related shorts between signal pins and the VBUS at elevated voltage levels.”
The KTU1108 is available in a RoHS compliant 1.3mm x 1.7mm wafer-level, chip-scale package (WLCSP).The KTU1108 is available and shipping now.
