The devices use few external components and provide multiple protection modes. They are a robust defense against overloads, shorts circuits, excessive inrush current, and reverse current. Current limit level can be set with a single external resistor. Applications with particular voltage ramp requirements can set dV/dT pin with a single capacitor to ensure proper output ramp rates. Many systems, such as SSDs, must not allow holdup capacitance energy to dump back through the FET body diode onto a drooping or shorted input bus. The BFET pin is for such systems. An external NFET can...
