Part Number: BQ25887
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: BQ25887 Hello Jing,
Is this answer regarding SNS is still valid? I just wonder the answer is 3years old and wish to clarify again.
If I used D4 as below, do you expect any problem?
Do I have to disconnect the net on Green box below?
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…
Part Number: BQ25887 I am looking at the BQ25887 datasheet (SLUSD89B) and have found in the graph of what stages of charging (sec 8.3.4.2, pg 20), also the Charging Safety Timer section (sec 8.3.4.6, pg 23), the safety timer is marked as CHG_TIMER[0:1…
Part Number: BQ25887 All the schematics I see for this has the system it's embedded into using the battery via the SYS pin of the chip. Does this path provide high current ~40A?
I plan to embed this into a drone to provide onboard charging and balancing…
Part Number: BQ25887 Ok, so my charger just keeps charging and charging. It's not stopping. Right now the current is 50 mA coming off the bench power supply that I'm using to feed it. This is a standalone product, so I've not queried the registers…
