Has the ON semicondutor logo. It is a custom marked part for an
unknown OEM. That ebay seller claims "100% tested before shipping.
Gurantee exchange if it is fault." so either they know what it is, or
they are lying.
Try to actually buy one. Those so called sellers list millions of
parts they've never seen. They copy lists from other component weseles,
looking for suckers. When you bite, they send out emails to everyone
they can think of to try and locate the part. Since a lot of the lists
were compiled from the indexes of databooks, there is a 99% likelyhood
that no one has any.
You can't have a sense of humor, if you have no sense.
It appears to be a custom part for an APC UPS.
"Smart UPS 620 (SU620INET) No. NS9424340482"
See this discussion:
The OP has correlated the pinout of the DB9M serial connector to the
pinout of the IC.
Contact pin DB9M - pinU4:
pin1 - pin15 SDI;
pin2 - pin4 SDD; <----- should this be SDO ?
pin3 - pin 5 ONBAT NO;
pin4, 9GND - pin7, 8 GND;
pin5 - pin9 LOBAT NO;
pin6 - pin6 ONBAT NO;
pin7 - pin13 REMOT IN;
pin8 - svoboden (= free, not connected)
