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…
Part Number: BQ25887 Could I get a review of the 2 cell charger schematic using the BQ25887 please? BATT is the positive side of the 2 cell battery and BATT_MID is the middle connection between the 2 batteries. I do not plan on using the SNS/SYS output…

I noticed my BQ25887 eval board, even with PGSEL tied to ground and 374Ohm ILIM resistor, is only outputting 1.3A as measured by my multimeter.
What would cause a lack of current for standalone mode? Would the lack of NTC thermister…
Part Number: BQ25887 We would like to use this part in a new design and we need to create also a testbench, to test if the battery charging works properly we usually put a resistive load in parallel with big capacitors on the connector where the battery…

I'm having the same issue as the person in this old thread .
Bought the BW25887EVM. Using a 2SP1 battery pack and using a bench power supply running at 5.00v / 3.00A Max. The eval board is pulling 2.5A from the power supply but…
Part Number: BQ25887 Hi team,
Have you seen any designs with the BQ25887 where there is a load placed directly on the battery terminals. Similar to the diagram below. Is it possible for the part to operate correctly with this configuration? Can the battery…
Part Number: BQ25887 I am not sure about the connection of SNS and BAT pin to the system, this is our schematic
From the datasheet it looks like the SNS pin is the output of the converter and that BAT pin has to be connected to the battery, am i right…
Part Number: BQ25882 Other Parts Discussed in Thread: BQ25883 , BQ25887 , BQ25886 The JEITA guideline was released on April 20, 2007 to improve the safety of charging Li-ion batteries. Each of the chargers in this family have a TS pin, which is used with…
