An integrated circuit can function within each device as a microprocessor, amplifier, or memory. Integrated circuits are created using photolithography, a process that uses ultraviolet light to print ...

Power Integrations has successfully completed an important series of tests for Power-over-Ethernet Powered Devices incorporating the company's DPA-Switch family of ICs.

Main power live interface circuit diagram. To avoid having to modify the circuit for each device being monitored, the circuit monitors the device’s AC power line directly. The resistor R1 lets a ...

Then there are the many different electrical interfaces that define the connections between circuits and equipment. The interface could be RS-232, RS-485, USB, Ethernet, or fiber.

To alter the circuit’s output-voltage level, IC 2, a 256-step Maxim MAX5400 digital potentiometer, controls IC 3, a Maxim MAX1658 adjustable-voltage linear regulator. Writing all zeros to IC 2 sets IC ...
