One of the most overlooked, but important performance characteristics of a capacitor used in power circuits is its equivalent series resistance (ESR). ESR determines the capacitor's I2R heating losses, which in turn impact the efficiency, pulse...
As IC manufacturers develop processing technologies allowing higher integration levels, they can double up on the functions included in a single package or shrink the package size. Two examples are the dual motor driver IC from Allegro...
