Part Number: BQ25173
Dear Sir
We are in a application to charge supercapacitor upto 7.5V 2Farad and fast charging time is required
Using a single BQ25173 for charging supercap upto 7.5V 2F will take 18.75 seconds from zero volts as per my calculation…
I estimate that you will need a 50F capacitor at 7.5V. This could be 3 X 150F 2.5V capacitors in series, other configurations are possible.
This capacitor bank would feed a DC to DC converter, possibly TPS63060 buck boost.
This would give you 5V at 1A…
Part Number: BQ25173 Hi,
For a design we would like to use the BQ25173 in combination with the IRM-01-3.3 to charge a 3V supercap to 2.7V.
The meanwell power supply has a voltage rating of 3.3 volts with a +/- of 2.5%. This means the power supply would…
Part Number: BQ25173-Q1 Hi colleagues,
If I have fully discharged supercap 0V and 16V as input I have 800mA set, I have 12.8W on this LDO. I think that we would run fast into a thermal protection situation since the thermal impedance is 71°C/W. What is…

Part Number: BQ25173-Q1 Hi Team,
I would like to use BQ25173-Q1 to charge the 3.6V battery. I'm not sure if there is anything difference between charge super cap and battery. May you let me know your comments?

Part Number: BQ25173 Hi,
We are evaluating the BQ25173 to charge a supercapacitor, but we have some doubts due to our type of application. In our case, we can't have the supercapacitor on the electronic board.
The main board has the BQ25173 connected…
