Part Number: BQ24278 Tool/software: Hello,
In all power bank ICs or battery charging ICs, there is an lim resistor that sets the maximum charging current. If I set it to its maximum limit, say 2.5A for the bq24278 IC, and the input power adapter (5V…
Part Number: BQ24278 The pin CD has very little description....Suggests that it is the IC Hardware Disable pin and places it into High Z mode....What does this exactly mean? Does the chip go into low power mode drawing very little current? Also does this…
Part Number: BQ24278 Other Parts Discussed in Thread: TCA9548A , Good evening.....
I keep my library parts in a local database and like to re-use footprints where possible. I have a TCA9548A part that uses a RGE0024C. I notice that this is the same footprint…
Part Number: BQ24278 Other Parts Discussed in Thread: BQ25606 Hi,
My electrical engineer has sugested the BQ24278 charger ic for an upcoming project, for the main reason that it doesnt need a host system.
But the datasheet says, dont use for new designs…
Other Parts Discussed in Thread: BQ24278 , BQ25896 , BQ24250 Thanks for quick feedback. I need to come up with a solution (may be SW) as there over 2K boards built. A few questions
1) VBATREG spec is not clear in BQ24278. Why 2 values for TA=25?
2) You…
The bq24278 is a spin of the bq24166/7. As document in the bq24166/7 datasheet, the IC has reverse boost prevention circuit. This circuit prevents the buck converter from working in reverse as a boost converter, pushing current back to the input. Unfortunately…
Other Parts Discussed in Thread: BQ24278 I completed BQ24278 test circuit with the following configuration:
Firstly, I drove bq24278 without battery connected. When both CD & CE/ was connected to Vcc, LEDs were on and Vsys was about 1.7V, where system…
Other Parts Discussed in Thread: BQ24278 Hi Jeff,
This is the third and final, hopefully, question about BQ24278. As I said before, I'll use the chip just for charging Li-Ion battery. I've asked how are the connections if system load is not present. I…
Other Parts Discussed in Thread: BQ24278 Hi,
I want to charge my li-ion battery with bq24278 without system connection. As I asked earlier, you told me that SW, SYS, and BOOT components should be still connected, and left BGATE unconnected. In this case…
Other Parts Discussed in Thread: BQ24278 Recently i'v met a problem when I was designing the charging circuit using BQ24278. The problem is that the IC seems not working,I checked the input is OK.and I read many Subjects in this community. I wonder…
