LS0505EVD22

LS0505EVD22 is a 5V, 5A eFuse with overvoltage and overcurrent protection. This integrated load switch provides robust input over-current protection to downstream circuit systems. The device comes with built-in over-voltage protection, and internal soft-start. The switch’s 50mohm low RDS(ON) minimizes the power loss of the system. In the event of input overvoltage, LS0505EVD22 immediately turns off the switch to prevent downstream system from stress of excessive high voltage. Set the current limit level with an external resistor. Internal soft-start ensures a smooth output voltage ramp up and limits the input in-rush current. Application includes Bluetooth headsets, wearable device, tablet PC, charging cable, battery devices, adapter powered devices.
