SiC FETs now include measures aimed at keeping losses down while managing fast switching waveforms. Dr. Anup Bhalla | UnitedSiC Silicon carbide (SiC) FETs have low on-resistances, fast switching speeds, and intrinsic diodes with low reverse recovery charge (QRR) and low forward-drop (VF) qualities. These qualities make SiC FETs suitable for use in active-front-end three-phase […]
High-voltage switch IC delivers 3 A to 64 channels
STMicroelectronics’ 64-channel high-voltage analog-switch IC delivers integration for advanced ultrasound systems, probes, piezoelectric drivers, automated test equipment, industrial automation, and process control systems. The STHV64SW comprises a shift register for logic control signals, self-biased high-voltage MOSFET gate drivers, and N-channel MOSFET switches capable of providing up to ±3A peak output current. The switches respond quickly, with 1.5µs […]
