  • Hi Zoey,

    A few comments:

    • The pullups on the PWRCTL outputs will enable battery charging.
    • What are SDA/SCL connected to?  They should not be connected to a system I2C bus unless they are in use since they have internal pulldowns.  If I2C or SMBUS is used the pullups should be 2.2K or less.
    • If the voltage ramp time is slow, the capacitor on GRSTz can be increased to 2.2 uF to increase the reset pulse width.



  • Hello JMMN,

    Thanks for your reply and I will pass these information to my customer.
