DS2764 Datasheet | Maxim Integrated

DESCRIPTION The DS2764 high-precision Li+ battery monitor is a data-acquisition, information-storage, and safetyprotection device tailored for cost-sensitive battery pack applications. This low-power device integrates precise temperature, voltage, and current measurement, nonvolatile (NV) data storage, and Li+ protection into the small footprint of either a TSSOP package or flip-chip package. The DS2764 is a key ponent in applications requiring remaining capacity estimation, safety monitoring, and batteryspecific data storage. - FEATURES Li+ Safety Circuit Overvoltage Protection Overcurrent/Short-Circuit Protection Undervoltage Protection 0V Battery Recovery Charge Available in Two Configurations: Internal 25m W Sense Resistor External User-Selectable Sense Resistor Current Measurement 12-Bit Bidirectional Measurement Internal Sense Resistor Configuration: 0.625m A LSB and ±1.9A Dynamic Range External Sense Resistor Configuration: 15.625m V LSB and ±64m V Dynamic Range Current Accumulation: Internal Sense Resistor: 0.25m Ahr LSB External Sense Resistor: 6.25m Vhr LSB Voltage Measurement with 4.88m V Resolution Temperature Measurement Using Integrated Sensor with 0.125°C Resolution 40 Bytes of Lockable EEPROM Option for Unique 64-bit ID Industry 2-Wire Interface with Programmable Slave Address Low-Power Consumption: Active Current: 60m A typ, 90m A max Sleep Current: 1m A typ, 2m A max - - - PIN CONFIGURATIONS TOP VIEW CC PLS DC SNS SNS SNS PS IS2 1 2 3 2 4 5 6 7 8 16 15 14 13 12 11 10 9 VIN VDD SCL VSS VSS VSS SDA IS1 - - - - - - - TSSOP 1 2 3 SNS PLS DC CC VIN VDD SNS PROBE VSS PROBE 4 A PS IS2 IS1 SDA B C D E F APPLICATIONS PDAs Cell Phones/Smartphones Digital Cameras ORDERING INFORMATION PART DS2764BE TEMP RANGE -20°C to +70°C PIN-PACKAGE 16 TSSOP SCL VSS FLIP CHIP (TOP VIEW ¾BUMPS ON BOTTOM) Selector Guide appears at end of data sheet, for additional options.
