: The chip continually measures current, voltage, and temperature.
: It provides protection against overvoltage, undervoltage, and overcurrent (both during charging and discharging). : The chip continually measures current, voltage, and
"2761x" is a technical term primarily associated with the , an integrated circuit developed by Analog Devices (formerly Maxim Integrated) designed for High-Precision Li-Ion Battery Monitoring . : Uses a 1-Wire interface , allowing multiple
: 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
: 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.
: To conserve power when the battery is not in use or the voltage drops too low, the device can enter a low-power state where monitoring is suspended. Practical Safety Tips for Li-Ion Batteries
