Product Overview

LS1205EVD33 is a LS1205ExD33 series eFuse with a programmable current limit and output voltage clamp. This integrated load switch provides an easy circuit protection to power the system. The devices use few external components and provide multiple protection modes. This is a robust defence against overload, short circuit, input voltage surge and excessive inrush current. The switch's 25mohm 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. Application includes HDD and SSD drives, adapter powered devices, PC / Notebook, FAN control, networking.
  • Wide input voltage range from 2.7V to 18V (TA = +25°C, VIN=5V)
  • External selectable input range and clamping output voltage threshold
  • Output discharging function, external programmable soft start time
  • External programmable current limit up to 5A
  • Short-circuit protection, enable control pin
  • Thermal shutdown protection and auto recovery
  • Quiescent current is 200µA (typ, TA = +25°C, VIN=5V)
  • Current limit program range from 1 to 5A (TA = +25°C, VIN=5V)
  • Soft-start time is 25msec (typ, CSS=100nF, TA = +25°C)
  • DFN3×3-10L package, junction temperature range from -40 to +125°C
