Part Number: BQ25173

Hello,

The customer uses BQ25173 to charge a supercapacitor with a capacitance of 2F and a voltage of 5.5V. How to configure the VREF and feedback resistor?

    1.) Feedback Resistors for 5.5V -- A possible solution is 665k (upper resistor), and 113k (lower resistor).

    2.) Voltage at STAT and /PG pin -- The absolute max voltage is 5.5V for the pins, VREF should be a voltage that below this point.
