Sofics announced today that its PowerQubic electrical overstress (EOS) technology has been chosen by eSilicon Corporation for a high-voltage solar power application.
PowerQubic technology will protect the 15 volt (V) interfaces on a new integrated circuit (IC) that eSilicon is creating for a customer who will use it in solar-panel power converters. The converters transform direct current (DC) voltage from the solar panels into standard alternating current (AC) voltage for residential and commercial use.
Sofics PowerQubic technology is designed to enhance reliability in high-voltage systems, such as automotive and motor controls, power management and conversion circuits. Sofics offers TSMC-approved PowerQubic solutions in 0.25 micrometre (µm) bipolar/complementary metal-oxide semiconductor (CMOS)/double-diffused metal-oxide semiconductor (DMOS), also known as BCD, and is currently developing others. All versions can be ported to other processes.
PowerQubic technology prevents latch-up and mitigates electrostatic discharge (ESD) and other forms of EOS, enabling reliability in high-voltage systems.
