The SY20808C20/D20 is an ultra-low RDS(ON) switch. It operates over an input voltage range of 2.5V to 5.5V. It has a current limit to protect the power source from overcurrent and short-circuit conditions.
Active high or low polarity options for enabling the part are available for flexibility.
The SY20808C20/D20 incorporates soft-start, overtemperature protection and reverse blocking functions. The OCB open-drain fault indicator can be used to signal the event to a system host.
The device is available in a standard SOT23-5 package.
