(apparently no longer made= ) 3F 2.7 volt capacitors have leaked onto circuit board. Easy enough to replace capacitors, however one IC has corroded pins. It is labelled U24. It is a 10 pin TSSOP package. Markings are either 0411 or 04TI. (hard to see) Followed by BBQ. Does anyone know what the chip is or how I might track it down? Thanks in advance.
