Part Number: BQ25505 Hi
The customer design with BQ25505, they set Vbat_ OV is 4.5V, Vbat_ OK_ HYST is 4.2V, but it is found that the super capacitor can be charged to 4.5V, while Vbat_ OK is always low.
Attached the schematic for your reference.
They…
Part Number: BQ25505 Hello!
There is a contradiction in the datasheet.
On page 5, in the Pin Functions table, it says that pin 6 needs to be connected to VSS via the IC's PowerPad.
However, in figure 40, the Layout Example, pin 6 is not connected…
Part Number: BQ25505 Hi,
I wanted to get footprint information for the BQ25505RGR IC and for that I went to the webpage : https://www.ti.com/product/BQ25505?keyMatch=BQ25505RGRR&tisearch=search-everything&usecase=OPN
In the section CAD/CAE symbol…
Part Number: BQ25505 Other Parts Discussed in Thread: BQ25100 , BQ24210 We use your chip BQ25505 chip as our solar charging IC for our recharging battery. This chip is in our mass product now. But with some new regulations, We need control the minimum…
Part Number: BQ25505 Hi,
My current design is using BQ25505, but the datasheet does not state MUX signal if primary battery is not connected. Will VSTOR keep internal reference to the secondary battery level even if it is lower than the VBAT_OK_PROG when…
Part Number: BQ25505 I am using a BQ25505 in an energy harvesting application. For reasons specific to the application, I need to periodically remove the load applied to the energy harvester for ~200 ms before re-applying it, and I want to do this without…
Part Number: BQ25505 Hi team,
Customer want to get the BQ25505 package info to set up their PCB library, we can't find in datahsheet, could you help provide the datasheet with package size info? Thanks.
Part Number: BQ25505 Other Parts Discussed in Thread: BQ25570 , Hi all,
I'm looking for the PSpice model of BQ25505 (or BQ25570) but couldn't find it in the documentations of the TI website. Can anyone help me?
Best regards,
Yeji
Part Number: BQ25505
In the datasheet of BQ25505, VDELTA = VBAT_OV - VIN(DC) is recommended to be set at a minimum of 400mV. Can you confirm VIN(DC) here means the VMPPT voltage level?
Also, would changing LBoost value be a solution to reduce maximum…
Thanks Jeff. In my design with BQ25505 I have set VBAT_Ok = 3V and VBAT_OK_Hyst = 3.1V.
At initial power up, is it suggested to connect solar cell first or the battery and why?
Considering answer above, which thersholds VBAT_Ok or VBAT_OK_Hyst does BQ25505…
