NTN5536A Gang Charger

[OneManShow]

Hi,

Would somebody out there have a diagram that you could share for this charger, or at the very least tell me what a
"185 61L75" I/C is? The I/C drives a npn transistor that drives a pnp transistor which is the charge regulator for the battery cup. Is there a generic replacement? The p/n I found on the board is 5235R01 and the date stamp is Jan 30 1991.

Thanks,
Sean

185 is Motorola's ID. 61L75 is the last four chars of the part number.

Hi Will,
I thought the p/n looked familiar, so I searched MOL and it returned 0 results. So, either the part is NLA or, there is a substitute p/n. My bet is that it is NLA. I would like to find out what the I/C does in the circuit and hopefully I can find a generic sub.

Thanks,
Sean
