: If a Li-ion battery catches fire, never use water or cover it with cloth; use a Class D fire extinguisher if available. DS2761 - Analog Devices
: Includes 32 bytes of lockable EEPROM for storing battery-specific data (like chemistry or capacity) and 16 bytes of SRAM for dynamic data.
: It measures current flow by monitoring the voltage drop across a current-sense resistor. It can be configured with an internal resistor or an external user-selectable one. : If a Li-ion battery catches fire, never
: Always use manufacturer-provided equipment and disconnect once fully charged. Heat : Avoid charging on soft surfaces like beds or pillows.
: Uses a 1-Wire interface , allowing multiple devices to reside on a single bus and minimizing the number of pins required on the battery pack connector. Technical Specifications Current Resolution 12-bit signed resolution; updates every 88ms Sense Resistor or external option Measurement Units Amps (with 0.625mA resolution for internal resistor) Full-Scale Range ±1.9Aplus or minus 1.9 cap A (with internal resistor) Supply Voltage Typically operates directly from the battery cell Operational Modes It can be configured with an internal resistor
: It provides protection against overvoltage, undervoltage, and overcurrent (both during charging and discharging).
: The chip continually measures current, voltage, and temperature. : Uses a 1-Wire interface , allowing multiple
The is a comprehensive battery management chip that combines high-precision data acquisition with safety features. It is used to monitor current, voltage, and temperature in Li-Ion battery packs, providing the necessary data for gas-gauging applications. Key Functional Components
