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…
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…
Hello,
I am confused by your results. Did the battery terminate at 8.42 V? Terminating at 4.23 V is well below the charge regulation. Did you mean the individual cell (of which there are 2) terminated at 4.23 V?
The best way to know is to perform an ABA…
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!

Part Number: BQ25886 Dear TI experts,
my customer tests BQ25886 on their own PCB.
During the test, they found that STAT pin goes high right after VBUS applied, and goes to low after 380ms.
please see the schematic and waveform.
As you can see, they…

Part Number: BQ25886 Dear TI experts,
My customer drew their first schematic with BQ25886. Could you review the schematic first?
and here are more questions ;
1. my customer will not use thermistor. Is it okay to float TS(7) pin? or just connect resistors…
