The IR25750LPBF is a current sensing integrated circuit designed for MOSFET, DirectFET and IGBT current sensing. It has integrated ESD protections and eliminates external current sensing resistors.The ...

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 ...

Current sensing remains a challenge and while most engineers use DCR current sensing it is notoriously inaccurate. So what can be done to improve accuracy? The buck converter is the most common power ...

In-circuit testers rely on bed-of-nails-type fixtures that give the tester access to every node (or net) of the printed circuit board (PCB). Using this access, the tester takes a divide-and-conquer ...

Resistor-based current sensing is simple, easy to use, low cost, extremely linear and requires no calibration. The statement that voltage across a resistor is directly proportional to the current ...

Abstract: An innovative current-mode DC-DC Buck Converter is presented by this paper, integrated with power switches and a novel on-chip current-sensing circuit for the feedback control loop. The ...

Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four terminal chips that will sense across a resistor in the ...

A range of manufacturing and production processes rely on current-operated relays to provide a continuously adjustable trip-current setting. They are able to protect mechanical apparatus from jam-up ...

What qualities are needed for current sensors in an automotive environment? Warren Pettigrew spells out the requirements. Today what is expected of automotive sensors is quite different to what was ...
