Part Number: BQ25887 Other Parts Discussed in Thread: BQ25883 Tool/software: Hi,
Is there a chip similar in form factor to the BQ25887 that supports both balancing and power path management?
My requirements are support for 2s, 5V input and configurable…
Part Number: BQ25887 Tool/software: Hi,
I'm looking at the BQ25887EVM and I had a few questions.
1. Are the input and output shunt resistors R1 and R6 necessary for operation? I didn't see the voltage drop across them connected back to the BQ258…
Part Number: BQ25887
Tool/software:
I am attempting to utilize the balancer 5 click( Balancer 5 Click | Mikroe ) which utilizes the BQ25887 in one of my projects. I am using it as a breakout board with my Arduino. The Arduino has successfully identified…
Part Number: BQ25887 Other Parts Discussed in Thread: BQ25882
Hi,
I noticed that BQ25887 has cell-balancing function, which is suitable for 2s cells charging application. But it does not support Power Path Management.
Other devices like BQ25882/3/6…
Part Number: BQ25887 Tool/software: Hey, I have a question about the calculation of the resistors for the voltage divider of the thermistor on page 23 of the data sheet. The values used for V_T1 to V_T5 seem inconclusive to me. In the table for the electrical…
Part Number: BQ25887 Tool/software: Hello,
I am thinking about using the BQ25887 for a project that will be powered by 2x 18650 Lithium batteries. I like this chip and have a few questions about usage of operation.
1. When the device is not being charged…
Part Number: BQ25887 Hi
The customer design with BQ25887, c urrently in the XBL stage of Android 13, the battery voltage needs to be read when starting the prototype, and the following process is used:
Read the voltage of a single battery. During debugging…
Hi Salinda,
1. Ground vias are more numerous.
2. Looks like there are significant more vias, this should help with the heat.
3. Looks like analog ground has been added. Please connect ILIM through analog ground like in BQ25887 EVM User Guide. Good job…
Part Number: BQ25887 I see that the BQ25887 has reverse cell protection based on a resistor between IC MID and middle point of 2 cell setup.
When connecting any 1 cell in reverse, the IC heats up incredibly. I only leave it like this for 1 or 2 seconds…
