Figure 12. REG Output Timing
For bq2960 family, an external REG_EN pin is available to enable and disable the regulated output function. To
enable both the regulated output and the undervoltage self-disable features, the REG_EN pin must be above V_IH.
A microcontroller can be used to control the REG_EN pin. Alternatively, connecting the REG_EN pin to the
bottom cell is another option to enable the regulated output function always.
