Using current mirror for current sensing in high current MOSFET applications significantly reduces power loss in current sensing circuit and lowers design cost by replacing expensive high power ...

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 ...

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 ...

Find a downloadable version of this story in pdf format at the end of the story. TYPICAL HIGH-SIDE, n-channel, hot-swap “soft-switch” systems use a charge pump to drive the gate of an external MOSFET ...
