Protection IC Datasheet  
LS12052BD33  
18V, 5A eFuse with Over-Voltage Protection and Blocking FET Control  
RoHS Pb  
Description  
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.
