Two process control signaling schemes were to be supported — the 0 to 10 VDC analog signal, and the venerable 4-20 mA current loop.

The simple addition of a transistor and resistor to the open-circuit drive overcomes this dilemma by limiting current through the drive transistor. Transistor Q2 provides the open-collector drive ...

The circuit shown is a simple current limiter and is recommended since it offers a higher efficiency than other transistor circuits. It works to limit the current through R_sense such that the ...

1. A simple, widely used current limiter consists of a current sensor (usually a low-value sense resistor), a control circuit, and a pass transistor.

Current sensing devices are often desired in the power supply lines of various circuits, such as battery-powered computers, battery chargers or critical circuits requiring thermal forecasting. Figure ...

A Simple Over-Voltage Protection Circuit for LED Drivers This boost circuit implements current mode control and senses the LED current via resistor R14. The output voltage is boosted to just over 30V ...
