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 ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

A voltage-to-frequency converter (VFC) can easily measure current flow and convert it to a digital signal understood by the timer/counter input of a microcomputer (µC) or microprocessor. It's a ...

Abstract: A new on-chip current sensing circuit for the over-current protection of the electronic ballast is presented in this paper. The proposed scheme increases the sense accuracy and noise ...

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 ...

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 ...

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 ...

Abstract: This paper presents an improved current-sensing circuit for boost converter. The proposed circuit replaces n-channel switching transistors with p-channel switching transistors to eliminate ...

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 ...
