Product Roundup

摘要

Power management ICs continue to make inroads in all designs, especially for battery-operated devices in automobiles, consumer electronics, industrial, and military applications. Some of the newest products include the STMicroelectronics STPM3x, which help prevent errors below 50 mA in energy meters and can prevent up to MWh of lost billings for customers. They help keep meter accuracy to a few mA and perform power-quality calculations on-chip, including rms voltage and current measurements, apparent energy computations, and under/ over voltage detection.
