Metal Detector uses Single IC - 12/18/97 EDN Design Ideas: The circuit in Figure 1 protects a power bus from a load short within a guaranteed 2 µsec; a short could otherwise pull down the bus, affecting other loads. The circuit also controls inrush current to bypass capacitors during hot-swap (hot insertion) , another situation in which bus voltage could otherwise experience a droop. You can individually set the two current limits. Power-on reset and logic controls allow complete µP interfacing. Design by Rachel and Steve Hageman, Hewlett-Packard, Santa Rosa, CA
