Hi Sir

May I know bq24610 datasheet page 24 Figure 17. Vreg What is the voltage?

is VREGN_REG REGN regulator voltage 6V?

    Hi Wang,

    In Figure 17, Vreg is the  voltage you charge your battery up to. You can usually set this  value  by changing the resistor divider at the  Vfb pin. The equation for is:

    Vreg = 2.1(1+ Rtop/Rbottom)

    Where Rtop is the resistor from Vbat to Vfb, and Rbottom is the resistor from Vfb to  ground. We usually recommend keeping  Rbottom at  100k Ohm, and adjusting Rtop to get the correct regulation voltage.

    For your second question, you are correct. REGN is an integrated  LDO set to regulate  at 6V.
