Atmel Announces ATA6870 and ATA6871, New Li-Ion Battery Management Chipset for High-Cell-Count Automotive and Industrial Applications

The ATA6870 and ATA6871 are new Li-Ion battery management chipset for high-cell-count automotive and industrial applications such as electrical/hybrid vehicles, e-bikes or uninterruptible power supplies. The ATA6870/71 chipset requires less external components than comparable solutions because it includes a hot plug-in capability, six integrated AD converters with a cut-off frequency lower than 30 Hz, saving external filters, and a stackable microcontroller power supply. The ATA6870 is the industry’s first battery management IC to include all functionalities required to control a high-cell-count Li-Ion battery including six precise 12-bit AD converters for voltage monitoring, cell balancing, cell temperature measuring, and unique features such as stackable integrated power supply for a microcontroller or hot plug-in capability. Since Li-Ion batteries are very sensitive against overcharging and deep discharge, they may burn or explode. To prevent this, Atmel provides a special safety strategy with its secondary protection device, the ATA6871…
