Part Number: BQ25887 Tool/software: Hi,
I'm looking at the BQ25887EVM and I had a few questions.
1. Are the input and output shunt resistors R1 and R6 necessary for operation? I didn't see the voltage drop across them connected back to the BQ258…
Part Number: BQ25887EVM When I connect the input power source and the 2 cells battery the circuit does not work, i think that QBLK is continuously triggered, here voltage waveform at PMID pin; voltage at VBUS is 5V constant
Here my schematic as reference…
Part Number: BQ25887EVM Other Parts Discussed in Thread: BQ25887 Hi my name is Babu
If we see in the evaluation module of BQ25887, there are small small holes, can you tell me what is that hole exactly is ? Is that hole is wear or something else?
Can you…
Part Number: BQ25887EVM Other Parts Discussed in Thread: BQ25887 , Hi,
My name is Babu, I am designing the PCB with BQ25887 IC. Regarding the component selection of capacitor and resistors, if we see in the evaluation module datasheet the different packages…
Part Number: BQ25887EVM Other Parts Discussed in Thread: BQ25887 Hi,
My name is Babu. Regarding sensing the temperature we have TS pin in the EVM module. In datasheet you have mentioned "temperature window". Can you tell me what is Temperature window you…
Part Number: BQ25887EVM Other Parts Discussed in Thread: BQ25887 Hi,
My name is Babu,
Can you provide me the gebber files for BQ25887 EVM, because in the datasheet of the EVM, the details/layout are not clear. Even if you have altium files do share it…
Part Number: BQ25887EVM Other Parts Discussed in Thread: BQ25887 Hi,
My name is Babu,
Can you tell what is the exact use of PMID pin in EVM module, do we have to connect the battery to the PMID bin for charging the cells?
If not please let me know what…
Part Number: BQ25887EVM Hi,
My name is Babu. Regarding sensing the temperature we have TS pin and reading the value in the TS-ADC registers. can you tell me how these values are read and how can we convert these values into the temperature in degree Celsius…
Part Number: BQ25887EVM Hi,
I am using several DC/DC converter from Ti and I am able to export the design from the Webench, which is a great time saving. I was curious if Ti can send the board files for BQ25887EVM in Cadence/Orcad.
Thanks,
Ashraf
Part Number: BQ25887EVM Hello,
I am unable to get the charging current about about 600mA through both cells. The input current max is around 1A @5V. The registers can write that high but the actual values do not change. I have tried two power supplies…
