                                                                                                      The DS2438AZ+T&R is a smart battery monitor in 8 pin NSOIC package. The device provides functions that are desirable to carry in a battery pack. It contains unique serial number, direct to digital temperature sensor which eliminates the need for thermistors in battery pack, an ADC which measures battery voltage and current for end of charge and end of discharge determination, a integrated current accumulator facilitates fuel gauging and which keeps running total of all current going into and out of battery, an elapsed time meter in binary format and 40bytes of non-volatile EEPROM memory for storage of important parameters such as battery chemistry, battery capacity, charging methodology and assembly date. Information is sent to/from DS2438 over a 1-wire interface, so that only one wire (and ground) needs to be connected from central microprocessor to DS2438. This means that battery packs need only three output connectors (battery power, ground and 1-wire interface).
