Description

The LS1205E integrated load switch provides an easy circuit

protection to power the system. The devices use few external

components and provide multiple protection modes. They are a

robust defense against overload, short circuit, input voltage surge

and excessive inrush current. The switch¡¯s low RDS(ON) helps to

reduce power loss during normal operation. Set the current limit

level with an external resistor. Protect against input over-voltage

events via 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.

They are available in low profile 10 leads DFN 3mm x 3mm package.
