The BQ78PL116RGZT is a PowerLAN Master Gateway Controller with PowerPump cell balancing technology. It provides 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. Balancing is possible during all battery modes: charge, discharge and rest. Highly efficient charge-transfer circuitry nearly eliminates energy loss while providing true real-time balance between cells, resulting in longer run-time and improved cycle life. Temperature is sensed by up to 4 external sensors and one on-chip sensor.
● Optimal cell management prevention
● Improved sensing of cell problems diagnosis
● Detection of event precursors
● Very low power consumption
● Accurate, advanced temperature monitoring
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
