Chip Overview
CXDR7584 is a high-performance, low-power battery power meter chip that supports 1 to 3 series connected lithium-ion battery packs. This chip adopts advanced GaugePack™ The hybrid algorithm, combined with Coulomb counting and open circuit voltage measurement technology, can accurately estimate key parameters such as battery remaining capacity, health status, charging and discharging time, and automatically compensate for factors such as temperature, aging, and self discharge, ensuring reliable battery data throughout the entire life cycle.
Core Features
1. High precision electricity estimation
The CXDR7584 is equipped with dual 16 bit ADCs for high-precision sampling of voltage, temperature, and current. Its GaugePack™ The algorithm can complete capacity learning without a complete charge discharge cycle, greatly improving user experience and system efficiency.
2. Multiple protection mechanisms
The chip supports programmable voltage, current, and temperature protection thresholds, with primary protection functions such as overvoltage, undervoltage, overcurrent, and overtemperature. It can also output a temperature signal through the/TGD pin to ensure that the battery operates within a safe range.
3. Flexible communication and configuration
Through a 2-wire communication interface that complies with the SMBus V1.1 standard, users can read battery status, configuration parameters, and access 96 byte non-volatile data flash. Support standard commands, extended commands, and manufacturer access commands to meet customized requirements for different application scenarios.
4. Low power management and multi-mode operation
The CXDR7584 supports four power modes: NORMAL, SLEEP, FULL SLEEP, and HIBERNATE, which can automatically switch according to the system state to minimize system power consumption. In HIBERNATE mode, the chip power consumption is as low as 6μ A, suitable for portable devices with extremely high battery life requirements.
5. Rich indication and control functions
The chip supports 3 or 4 LEDs for power display and has pin output functions such as charging status indication, low battery alarm, temperature alarm, etc. Users can control the display behavior through buttons or commands to enhance the human-computer interaction experience.
