Current Limiter Offers Circuit Protection with Low Voltage Drop (.PDF Download)

    April 18, 2016

    There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a simple low-value resistor; since the voltage across it is proportional to the current, this voltage can be used to control the current flow through the pass transistor...
