The SY20807 is a current-limited P-channel MOSFET power switch designed for USB load-switching or hot-plug applications. Its ultra-low RDS(ON) and current limit protect the power source from overcurrent and short-circuit conditions. An external resistor is used to configure the current limit threshold between 0.2A and 2A. An opendrain output can be used to detect fault events.
The device incorporates overtemperature protection and reverse blocking functions.
Different versions of the part, SY20807B/C/L/Z, are available in 2mm x 2mm DFN and SOT23-6 packages.
