BQ78PL116 PowerLAN Master Gateway Controller With PowerPump Cell Balancing Technology
BQ78PL116 描述
The bq78PL116 master gateway battery controller is part of a complete Li-Ion control, monitoring, and safety solution designed for large series cell strings.
The bq78PL116 along with bq76PL102 PowerLANTM dual-cell monitors provide complete battery-system control, communications, and safety functions for a structure of three up to 16 series cells. This PowerLAN system provides simultaneous, synchronized voltage and current measurements using one A/D per-cell technology. This eliminates system-induced noise from measurements and allows the precise, continuous, real-time calculation of cell impedance under all operating conditions, even during widely fluctuating load conditions.
PowerPump technology transfers charge between cells to balance their voltage and capacity.
