General Description
The RY2122 Power Distribution Switch features internal current limiting to prevent damage to host devices due to
faulty load conditions. The RY2122 develops ultra-low on-resistance switch with programmable current limiting to
protect the power source from over current and short circuit conditions. It integrates the over temperature protection
and discharges the output capacitor during the shutdown. In case the output is pulled higher than the input voltage
under the shutdown, the RY2122 can block the current flowing from the output to the input. The RY2122 is available
in SOT23-5 package.
