Typical Application


The SY20807L is an ultra-low RDS(ON) power distribution switch with 2A adjustable current limit to protect the power source from over current and short circuit conditions. It incorporates latch off function under over temperature protection or over current protection. And it has reverse blocking function to prevent reverse current flow from OUT to IN.

The device has a 150Ω pull-down resistor for quick output discharge when the switch is turned off.
