Abstract
- The article discusses the ability of a digital-driver circuit to provide a proportional drive for a solenoid and eliminating the need for a microcontroller or a programmable logic controller (PLC) in the U.S. The authors stated that U2, a 350-mA driver with built-in analog and pulse-width-modulation (PWM) dimming control has been connected directly to the solenoid terminals. Meanwhile, U1, a 32-tap, nonvolatile and linear-taper digital potentiometer has been connected as a variable resistor. Moreover, to guard its output against overcurrent and short-circuit conditions created by a defective solenoid or shorted leads, U2 provided indirect short-circuit and thermal protection.
