LS12052BD33 18V, 5A eFuse with Over-Voltage Protection and Blocking FET Control Datasheet
■The LS12052BD33 family of integrated load switches provides an easy circuit protection to power the system. The device uses few external components and provides multiple protection modes. They are a robust defense against overload, short circuit, input voltage surge, excessive inrush current and reverse current blocking with an external NFET. The switch's low RDS(ON) helps to reduce power loss during normal operation. Current limit level can be set with a single external resistor. Input over voltage events are protected by internal clamp circuitry to a safe output voltage. Programmable soft-start controls the slew rate of the output voltage to limit inrush current during plug in. It integrates thermal fold-back function and over temperature shutdown protection. The BFET pin is provided to drive an external NFET which can be connected "Back to Back" with the LS12052BD33 output. The external NFET gate is driven by BFET to prevent current flow from the load to the source. LS12052BD33 is available in small DFN 3mm x 3mm-10 package.
