Other Parts Discussed in Thread: BQ24298 , BQ24195L , BQ25616 I would like to have suggestions for single cell LiPo battery charging ICs that are similar to BQ24195L/BQ24298 for the application of GSM/cellular internet connectivity. The main feature required…
Part Number: BQ24298 Other Parts Discussed in Thread: BQ24296M
When I use the ic with default settings for charge current limit and with an adapter that can offer curretn up to 3A the current limit should be at about 2A. But if I replug the power connecter…
Part Number: BQ24298 Other Parts Discussed in Thread: BQ24296M I have copied the typical application design, and followed the PCB layout guidelines, however Vsys remains unregulated. I always measure vbat voltage. I have checked my schematic symbol, footprint…
Part Number: BQ24298 I finally understand why Vsys is not regulated with no VBUS present
Datasheet 8.3.1.2 "Power up from battery without DC source" says that on power up, if only the battery is present and no DC source then BATFET connects VSYS to BAT…
Part Number: BQ24298 Hi, I'm using the BQ24298 CI of power management for a USB port. When I connect VBUS = 5.05v, V_SYS is around 1.34V. Occasionally I made a short circuit between REGN and SW, and the V_SYS went to 4.42v, but when I restart the V_SYS…
Part Number: BQ24298 Other Parts Discussed in Thread: BQSTUDIO Can you verify that I am understanding the datasheet correctly?
If I hardwire the PSEL and OTG pins for a 100mA input current limit (PSEL - HIGH, OTG - LOW), I can raise that limit later using…
Part Number: BQ24298 #1 I would like to know if I can expect a System Current >3A with only a USB-Power Supply (no Battery) and a System Current >3 with only a battery (no Power Supply) connected?
#2 If I have no battery connected can I programm…
Part Number: BQ24298 Tool/software: Linux Hi,
I am currently doing HW bring-up for a custom board which has a bq24298 battery charger. But find find any Linux compliant driver for this charger. Is there another driver which is compliant with this chip…

Part Number: BQ24298 Working conditions:
1.Micro USB charging with 26650 5000mAh lithium battery;
2. Do not use the OTG function.
Please help check:
1.PSEL is pulled down directly, not limited to standard USB charging.
2. Whether the design of QON, OTG…
