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 ...

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 ...

Linear Technology Corporation introduces the LTC4234, a 20A Hot Swap™ controller with integrated MOSFET and current sensing, providing a small footprint hot-plug solution for high density circuit ...

Mission critical servers and communications equipment must continue to operate, even as circuit boards and cards are plugged-in or pulled-out for maintenance and capacity adjustment. Hot swap ...

Seeking something-or-other, I came across a high-side current sense circuit that I had never noticed before. Here it is (right), in an app note for the OnSemi NCP3020A buck dc-dc converter controller, ...

The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...

Engineers who design circuits for automotive equipment, industrial devices, test-and-measurement instruments, and solar-power inverters often must measure supply currents and in most cases, they pass ...

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 ...

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 ...
