PRODUCTION DATA
The device integrates internal cell balancing MOSFET (CBFET) across each CB channel to enable passive cell balancing. The balancing current is determined by the cell voltage, the external resistor in series with the CB pin, and the internal CBFET Rdson, RDSON parameter. The following equations calculate the effective balancing current with or without adjacent CBFETs being on. Cell balancing can run in ACTIVE or SLEEP mode.
