Part Number: BQ25173-Q1 Tool/software: Hello,
I would like to use the BQ25173-Q1 with the maximum possible output voltage (10.5V). If I select FB_H = 402K 1%, FB_L = 33K 1%, I calculate the output voltage will be between 10.25V and 10.85V (nominal 10…
Part Number: BQ25173-Q1 Tool/software: Hello Team,
In our design we would be going to use BQ25173QWDRCRQ1 IC ,We have created design can you please review it.
Vin : 5V
Regulation Vout : 3.3V
Charging regulation current Iout : 0.5A

Hello
The BQ25173-Q1 would not be a good fit for this application. It is a linear regulator with no boost capability.
Low input voltage from the battery, 2.5V-3.2V will make it challenging.
The TPS 923610 may be an option and will change title.

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…
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-Q1 Other Parts Discussed in Thread: BQ25173Q1EVM I have a couple of questions about BQ25173-Q1 charger IC.
In the evaluation module user guide (BQ25173Q1EVM), I noticed a P-CH MOSFET (Q1) being used; however, in the charger IC…
