Other Parts Discussed in Thread: BQ24251 Please let me know about bq24251 taper current setting.
When the device is not in Host mode, I think taper current becomes 10% of charge current set by external resistor. When device receives I2C command, device…
Other Parts Discussed in Thread: BQ24251 , BQ24297 , BQ25890 Hello,
I was looking at the BQ24251. It contains all the attributes I was looking for in a battery charger that can detect the USB host current capabilities. I can access its status registers…
Other Parts Discussed in Thread: BQ24251 Hello,
will setting Register2.Reset reset also Register1.Fault (and also buffered faults)?
After PG of Bq24251 goes low I reset Bq24251 (writing Register2.Reset with one) however even after reset, I'm still…
Hi Wenjia,
I have question about D+/D-detection for SDP with good battery.
By referring Fig.19 in datasheet, bq24251 goes to Hi-Z mode at SDP detected and battery is good. Then does it go to Hi-Z mode after forced D+/D- detection by DPDM_EN bit? …
Other Parts Discussed in Thread: BQ24251 Hi
I'm using a bq24251 to charge my battery and power my system.
I've already using it on another product, without problems, but on my new product, somehow it's not working accordingly.
Setup:
R_ILIM =…
Your idea about reading a know register that was changed from default would work. Or you can read Register 1 bit 7 WD_FAULT and if it is a 1, then you are in standalone.
The USB_DET bits retain the detected status. Forcing a manual detection does not complete (i.e., the status will not change and the bit will not clear) if the current status DCP, SDP with weak battery or CDP with weak battery. DCD can take up to 900ms…
Other Parts Discussed in Thread: BQ24251 Hello,
I have some questions regarding the bq24251 D+/D- detection algorithm.
(1) The datasheet states that the D+/D- detection algorithm is only active when the device is in standalone mode (e.g. the host…
