Part Number: BQ25886 Hi, TI expert
A customer is considering the BQ25886 and has a few questions.
Looking at the datasheet of BQ25886, it appears that BC1.2 is supported.
According to the document, if the input is 5V and the charging current is 2A, it…
Hi Bill
Thanks for your reply.
Bill Johns said: In your test is there a system load?
Yes, there is a system load during test.
This picture shows the waveform measured by BAT of the circuit connected to the load.
This is the BAT waveform without load

Part Number: BQ25886 Hello, I am new to TI power management family. I made a custom board with 2 parallel Li Ion batteries (3.7v 5200mAh) and USB-C I/P on VBUS (Adapter specs 5V, 2A)
but getting the O/P of 3.1V from SYS Pin with drop of approx. 400 mV…
Part Number: BQ25886 Hi Guys,
we are developing a 2S lithium battery (700mA/h) charger integrated in our device and I have selected BQ25886.
The device is charged with main wall mount charger (not problem in this case) bat also with commercial power bank…
Part Number: BQ25886 Dear TI experts,
My customer did EMI test with their own PCB using BQ25886.
They added C57 and R77 in the schematic below ;
and latest test result is as follows ;

Could you recommend the initial values of resistor and…
Bill Johns said: I am checking on this questions:
Also to double check:
1.) Standalone IC no I2C
2.) Input capable to give 5v/9v/11v/12v
3.) Charge 2S1P/2S2P Li-Ion cells or smart batteries.
4.) Vout = 8.4V , Iout = 1A, Ilim = 2.0A
Hi bill,
I just want to…

Hi John
Yes 100uF should work also.
I have been looking at how to prevent the overload and voltage dip that is causing the problem -- but have not had any luck at this point.
Part Number: BQ25886 Hi team,
Have you noticed that if there is p2p part with BQ25886RGER? We want to promote BQ25886RGER but customer insisits that must have p2p replacement. Thanks!
