Isolation technology helping solar power connect to grid
by Rudye McGlothlin, Silicon Laboratories Although solar cells were invented some 60 years ago, solar technology is just now becoming a mainstay energy source for utility operators as they move to offload fossil fuels and incorporate more renewable energy sources. Despite a slowdown in 2018 after a reduction in solar feed-in tariffs in several countries, […]
TVS diodes provide 8-kW peak pulse power dissipation in a space-saving package
A new series of higher surge TVS Diode products come in an DO-214AB package. The 8.0SMDJ series is optimized to protect sensitive electronic equipment from transient voltage induced by lightning and other voltage events. Because it combines up to 8,000 W of peak pulse power dissipation in a compact DO-214AB SMC package, the 8.0SMDJ series […]
LED driver ICs optimized for instrument panel backlighting
Rohm announced the availability of the latest LED driver IC, the BD81A76EFV-M, optimized for LCD backlight in instrument cluster, center information displays and car navigation. Unlike conventional drivers with 4 channels that support LCDs up to 8”, this provides 6 channels of output (with 120mA per channel) that can support LCD panels of up to […]

Littelfuse, Inc. announced a new series of higher surge TVS Diode products in a DO-214AB package. The 8.0SMDJ series is optimized to protect sensitive electronic equipment from transient voltage induced by lightning and other voltage events. Because it combines up to 8000W of peak pulse power dissipation in a compact DO-214AB SMC package, the 8.0SMDJ […]
Dual-drive output driver IC efficiently toggles between two slew rates for low EMI motor drives
Analog Devices, Inc. announced a simple power solution that maximizes efficiency and minimizes electromagnetic (EM) emissions of motion systems as customers migrate to higher density automation. The ADuM4122, an isolated, dual-drive strength output driver that uses iCoupler technology, empowers designers to harness the benefits of higher efficiency power switch technologies. Electric motor-driven systems account for […]
Distortion-cancelling high-voltage LED Driver handles up to 80 W
Featuring a novel distortion-cancelling input-current shaping (ICS) circuit, the HVLED007 AC/DC LED driver from STMicroelectronics enables energy-saving solid-state luminaires to comply with increasingly stringent lighting regulations. The HVLED007 implements a peak current mode PFC control optimized for isolated high-power-factor quasi-resonant flyback converters. The ICS ensures an effectively sinusoidal input waveform with very low total harmonic distortion […]
Multilayer varistors optimized for automotive Ethernet
Multilayer varistors (AVRH10C221KT1R5YA8) for automotive Ethernet have a high ESD robustness for use in especially hostile environments. The new addition to the AVR series from TDK provides reliable ESD protection up to 25 kV (IEC61000-4-2). Moreover, thanks to the extremely precise multilayer technology and optimized manufacturing process, the new chip varistor features a low capacitance […]
Precision-resistor devices simplify thermal sensing
Riedon has introduced three new product lines leveraging its precision-resistor knowhow to simplify thermal sensing and monitoring, including miniature self-controlled heaters and resistance temperature detectors (RTDs). The PTC series of miniature heaters are positive-temperature-coefficient devices that stabilize quickly at 100°C-125°C depending on voltage and power rating. The PTC’s compact 9mm-high aluminum housing has a flat […]
