I am looking for a specific chips datasheet but am not having much luck in my search. The chip is used in a trigger mechanism, and although the chip is apparently widely available, no vendor has a proper datasheet for it. The chip is an CPX94 SOP8, with 9221 written below the CPX94. It connects to a MOSFET so I was looking to get its pinout. I'm not sure if this chip is now considered obsolete and that's why it's so hard to locate.
Below is the mostly complete setup, less the MOSFET and switch.
