Part Number: BQ25504 Other Parts Discussed in Thread: BQ2982 Hello,
I'm deisgning a new project and i will use an BQ25504 to charge a battery.
How can i protect this against user reverse connection of battery.
Regards.
Part Number: BQ25504 Other Parts Discussed in Thread: BQ25570
We're having a bit of trouble getting the BQ25504 to come out of cold start properly. We have a low power bluetooth design (schematic attached) powered from the BQ25504 which is charging a…
Part Number: BQ25505 Other Parts Discussed in Thread: BQ25570 , BQ25504 , Hello. The BQ25570 circuit I asked you about earlier works well because the problem has been solved.
When applying mass production products, the circuit is changed, so the output of…
Part Number: BQ25504 Hi Team,
Were can I find the BQ25504_TRANS.LIB. I have checked the TI website but I could not find it.
Can you please provide the file?
Thank you.

Part Number: BQ25504 Other Parts Discussed in Thread: TINA-TI , TPS63900 Hi There,
I am building an energy harvesting system that uses BQ25504 as a first stage followed by TPS63900. I am unable simulate the systems since the BQ25504 only has model files…
Part Number: BQ25504 I'm trying to develop an energy harvesting app.
I intend to use VBAT_OK as a simple comparator output for VSTOR, and the threshold should be set below the VBAT_UV voltage. But the datasheet says, "VBAT_OK_PROG threshold must be…
Part Number: BQ25504 Hi, I found several problems when using BQ25504, forgive my English expression.
1. I don't need battery overdischarge detection, ie VBAT_UV is not programmed and that pin is left floating. During charging, once the battery voltage…
Part Number: BQ25504 Hi teams:
Solar charging chip bq2504. The specification describes that the maximum boost swtich frequency is 1MHz.
When the chip works, the output voltage is adjusted through PFM mode.
Ask:
1. How does the chip control the boost operating…
Hi Theagainmen,
The charger is discontinuous mode, PFM boost converter. So, like all boost converters and especially one in DCM, there is no easy formula to compute exact output power so we have use efficiency estimate and power balance. The max average…
