Part Number: BQ25886 Other Parts Discussed in Thread: BQ25887 Tool/software: Hi, I have few questions regarding BQ25886RGER.
What will be the SYS voltages if single cell lipo max voltages are 4.2V i.e. Total 8.4V
Is SYS voltages are regulated or simply…
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…

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…
Trying to duplicate your test set up.
Is the scope capture with customer adapter or power supply?
Checking your test condition on the BQ25886:
UPDATE --Any jumpers different from factory setting?---I used jumper settings from video for additional test…
