The SY20823 is a dual 4A ultra-low loss load switch designed for intelligent power distribution in computers or portable electronics. The programmable turn-on delay facilitates proper power sequencing during mode transitions, while the programmable ramp-up time limits inrush current. Integrated over-temperature and short circuit protection enhance overall system reliability.

The SY20823 is available in a compact DFN 2mm x 2mm package.
