I'm trying to find a datasheet and identify this part, google hasn't helped me too much. Its marked as "5252F" and is a thru hole, 4 pin device SIP type packaging. The board has it marked as IC1, but I'm not sure if its a IC or FET

Knowing a bit more (or even anything whatsoever) about tye circuit
that it was in would help, but, this seems like a likely candidate

These are voltage detector IC's. This is a 5 pin smd version but one
pin is connected to substrate and is unused.
A ..5252 would be 5.200 Volt. MAY also have "PN" on the pkg.

A check whether the device would functionally fit your circuit would
help confirmordenythatitistheonenosirewehavenonukesaboardbutwearenotallowedtotellyou.

looking for BD52 on Digikey shows 6-LSOP AND 5-VSOF packages. .
