描述 Description

The LS2406ERQ23 is an advanced 28V 6A rated current limit

switch which provides overload, short circuit, input voltage surge,

excessive inrush current, over-temperature and reverse current

protections to the system. The built-in 24mΩ ultra low RDS(ON)

power switch helps in reducing power loss during normal

operation. Current limit level can be set up to 6A. with an external

resistor. The LS2406ERQ23 integrates thermal fold-back function

and over temperature shutdown protection. The LS2406ERQ23

has all time reverse current blocking function regardless of the

enable signal EN logic states. A fast role swap function is also

implemented to comply with the timing requirement defined in the

USB Power Delivery Specification. The integrated input and output

discharge function which allows the voltage levels at the input and

output ports to be discharged to meet the requirement of the USB

Power Delivery Specification. The LS2406ERQ23 is available in

low profile 16 leads QFN 2.5mm x 3.2mm package.
