I have a old battery charger using a Philips TEA1100 chip. It works well for NICAD but not suitable for Metal Hydrides as the delta V sensitivity is 1% of battery voltage. Using a Zina diode to increase the sensitivity would not help much as it is used for charge 6-cell and 10-cell battery packs. It looks to me that TEA1101 is an ideal replacement for it. TEA1101 has a sensitivity of 0.25%. However, Philips no longer makes them and our local supplier does not have them. Now my questions: (1) Do you know nay supplier that may still stock them? (2) Any replacement chip from other manufacturers? Any relevant comments and suggestions would be appreciated. Regards, Sam Yang
