Resumen del producto

The BQ77PL900DL is a five to ten series cell Lithium-ion Battery Pack Protector. The integrated I²C communications interface allows the protector also to be as an analogue front end (AFE) for a Host controller. The BQ77PL900 integrates a voltage translation system to extract battery parameters such as individual cell voltages and charge/discharge current. Variables such as voltage protection thresholds and detection delay times can be programmed by using the internal EEPROM. The battery pack protector can act as a stand-alone self-contained battery protection system (stand-alone mode). It can alternatively be combined with a host microcontroller to offer fuel gauge or other battery management capabilities to the host system (host-control mode). The protector provides full safety protection for overvoltage, under-voltage, over-current in discharge and short-circuit in discharge conditions. No external components are needed to configure the protection features.
