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 ...

The accuracy of a 4-20 mA transmitter depends on the integrity of its current-loop path, which must be free of shunt paths and ground loops, both within the transmitter and external to it. External to ...

Maxim has introduced a bi-directional current sense amplifier with pulse-width modulation (PWM) edge rejection. Called MAX40056 it is intended to reduce vibration in motor drives. The claim is that it ...

Digital control of switch-mode power supplies (SMPSs) is becoming practical thanks to the evolution of low-cost, high-performance devices with peripherals designed for power-conversion applications.

Servo motors are used in many areas in these days like automation technology, robotics and camera auto focus and may other areas. Majority of these applications require precise motor control of servo ...

LED-driver circuits can be dimmed by applying a variable duty cycle (pulse-width modulation, or PWM) to the LED. PWM exploits LED behavior: At higher current levels, the LED’s light output is higher ...

Every day engineers design products that employ single-phase induction motors. Speed control of single-phase induction motors is desirable in most motor control applications since it not only provides ...
