Part Number: BQ25790 Other Parts Discussed in Thread: BQ25798 According to the datasheet, I think the Rsns serves as the input current detection. However, this block diagram also shows another element near VBUS PIN to detect input current. So I would…
Part Number: BQ25790 In the block diagram, there is a resistance between VBUS and PMID, I would like to know if there are any other element. I have also measured the Vdrop between VBUS and PMID, which shows a 0.58V drop from PMID to VBUS, and the circuit…
Hello Michael, How can I retrieve the status and faulty register values using the cat command? If I check cat /sys/class/power_supply/bq25790-charger/status , it shows 'discharging' always. How can I troubleshoot and resolve this? and can you please…
Part Number: TPS25750 Other Parts Discussed in Thread: BQ25790 ,
Hello, we have a TPS25750 / BQ25790 chipset in a 2S1P integrated battery pack device currently under development. To date we have not been able to read battery voltage and other BQ registers…

I have a PD controller TPS25750 with a Charger BQ25790 that is charging a battery pack managed by the BQ40Z50. I have a few issues with each of these devices…
Part Number: BQ25790 Other Parts Discussed in Thread: TPS25750 Hi BQ team,
A customer is interested in using BQ25790 with TPS25750.
TPS25750 has below resistor values depending on what source is connected.
How does BQ handle current limit when combined…
Part Number: BQ25790 Can we get continuous 5V output from BQ25790 using 3.7V Li-ION Battery and also during charging? Our Processor board needs 5V.
We wanted one IC solution so if BQ25790 is sufficient or Is there any other single IC solution you can s…

Part Number: BQ25790 Other Parts Discussed in Thread: TPS25750 Hi team,
Let me summarize the operating flow of the TPS25750-BQ25790 in different use-case and please point out if my understanding is wrong. Especially the behavior of BQ25790.
Without MCU…
Part Number: BQ25790 Hi team,
Set (TWARN THO0) (TCOLD -TCOOL) to stop charging in the BQ25790 register. On hardware, the pull-up resistor RT1 = 5.3K for TS, the pull-down resistor RT2 = 31.1K, and the RTC uses 10k. RT(60°) = 3.02K, RT(0°C) = 27.28K. Charge…
