NS2201X Description:
    NS2201X series is an input overvoltage protection chip with built-in overvoltage/overcurrent/overtemperature protection function and input UVLO latch function. In case of input abnormality, it can disconnect the OUT port and IN port of the system, effectively protecting the downstream circuit from damage and improving the application reliability of the system.
    The NS2201X series offers two pin packaging options, NS2201A and NS2201B, both using the standard SOT23-3L packaging format.

NS2201X Features:
Maximum input voltage: 40V
Internal preset 1A load overcurrent OCP protection
