May 27, Texas Instruments Inc. announced a battery management ICs, and its rechargeable lithium-ion battery not only extend the life of groups, but also to maximize the hybrid electric vehicles, power tools, and uninterruptible Power supply (UPS) applications, the effective energy.
Stackable bq76PL536 battery monitor, integrated balancer and protector ADC support independent battery voltage and temperature protection, power balance and communication between the chip separation. The device can measure the battery cell voltage is smart to support the error of 1 mV accuracy, fully meet the new lithium-ion batteries of various chemical components of demand.
In addition, bq76PL536 also against overvoltage, undervoltage and over-temperature conditions to provide comprehensive secondary protection. Exceeds the safety threshold, the device will be set independent of the failure of the normal communication channel with the alarm output. Configure or enable the protection feature without the need of external components.
Key Features and Benefits
• ± 1 mV typical voltage measurement error can increase the precision to determine the remaining battery capacity monitoring accuracy, the efficiency of power balance and system security;
• for overvoltage, undervoltage and overtemperature protection integrated two-stage components without increasing the cost, can improve security;
• contribute to monitoring of the vertical stack can be up to 192 units, IC without external isolation between the components;
• 1 Mb / s high-speed serial peripheral interface (SPI) bus can be run between each bq76PL536, to achieve reliable communication;
• AEC-100 production flow in automotive applications, reliability and measurement;
• driver power balance state of charge by maintaining a balance with the capacity to expand the effective capacity, extend battery life.
