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.
