Part Number: BQ25710 Other Parts Discussed in Thread: PMP22419 , CSD87355Q5D Using the reference materials for the PMP22419 board from the official website, I hand-soldered a motherboard myself and used the BQ25710, following the reference materials exactly…
Part Number: BQ25710 Tool/software: Hi Team,
From datasheet, I can find below description for learn mode. Beside that, is there any more detailed introduction material for learn mode?
When the device is in learn mode, 4 switching MOSFETs are not switching…
Part Number: BQ25710 Other Parts Discussed in Thread: BQ25770 Tool/software: Hi team,
I want to know when BQ25710 move from Buck to Buck-boost and Buck-boost to Boost vice versa. Competitor's charger depict visible image like Vin=90%*Vsys is the transition…
Part Number: BQ25710 Tool/software: Dear TI Engineer,
When testing BQ25710, we found that when the equipment was turned off, the VSYS will loses power after about 20 seconds of unplugging the adapter and recovers after 3 seconds.
The schematic is…

Part Number: BQ25710 Tool/software: Hi team,
In our test, we set charge current (reg 0x14) as 4A~4.28A and monitor the battery charge current (reg 0x24).
However, we noticed battery charge current was dropped to 192mA unexpectedly by checking reg…

Part Number: BQ25710 Other Parts Discussed in Thread: BQ40Z50 , , TPS25730 , BQ25730 , BQ40Z50-R2 , PMP41013 , TPS25751 , BQ25720 Hi Texas Instruments team, I am working on a charging concept where we actually integrate USB PD charging into our device…
Part Number: BQ25710 Tool/software: hello,
We define REG0x3F=0x7F00 for the maximum input current limit (6350mA).
We have a load which might source more than 6.4A (RMS value).
Can we allow a higher than 6.4A current limit or disable the current…
