Two new Power over Ethernet (PoE) Powered Device (PD) families called the Si3406x and Si3404 families include all necessary high-voltage discrete components on a single PD chip. The new PD ICs support IEEE 802.3 at PoE+ power capabilities, flexible power conversion options exceeding 90% efficiency, robust sleep/wake/LED support modes, and superior EMI immunity. These capabilities […]
Isolated FET driver family aims at relay replacement apps in industrial and automotive uses
Developers have traditionally used EMRs and optocoupler-based SSRs in switching applications, and both technologies have limitations. EMRs are costly, slow, bulky and noisy. These drawbacks are driving double-digit growth in SSR usage, but even SSRs pose challenges. Optocoupler-based SSRs have inherent limitations such as shorter lifetimes due to LED aging, reduced performance and stability at […]
Isolated gate drivers incorporate protection for HV IGBTs
Silicon Labs has expanded its ISOdriver portfolio with a family of isolated gate drivers designed to protect sensitive insulated-gate bipolar transistor (IGBT) switches in power inverter and motor drive applications. The new Si828x ISOdriver family provides industrial-grade isolation (5 kVrms withstand), best-in-class feature integration including an optional dc-dc converter, the industry’s fastest desaturation detection, superior timing […]
