NiMH battery charger chip EW78P259NSO14J

[Andre Majorel]

Opened a Sanyo NC-MQN06U Ni-MH battery charger. The charging
seems to be done by 4 half-watt resistors and a 14-pin SMT chip :
EW78P259NSO14J. Does anyone have any information about that
chip ?

There is an EM78P259N micro-controller by Elan but it has 18 or
20 pins.

Thanks in advance.

If it is a microcontroller, it will have a proprietary program burned into
the chip. Even if you could get the a blank chip, the manufacturer of the
charger would not give you the program.
Requesting a chip from the charger manufacturer will probably get you no
ware.
Buy a new charger dude!
