Figure 1 is a generalized block diagram of a multichemistry battery charger. A COP8ACC5 µC handles its key charging features. The µC is available in a 20-pin (15 I/O pins) SOIC or a 28-pin (23 I/O pins) SOIC/DIP. It contains 4 kbits of internal ROM. visit page.
The controller`s A/D inputs monitor the battery-voltage pin, ID pin, and thermistor pin. For more complex charging systems, you can add external EEPROM via the Microwire serial interface. Such an external EEPROM might be useful for storing battery-sp visit page.
