Targeting the fractional horsepower DC motor drive market, the Apex Precision Power SA306-IHZ and SA57-IHZ embark as the industry's highest-current PWM ICs, delivering up to 5A of continuous current ...
This design idea reprises another “1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 ...
Accurate high-side current sensing is essential for automotive-control systems, such as those for EPS (electric power steering), automatic gear shifting, transmission control, engine fuel-injection ...
Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...
