Hi Ning,
Thanks for the comments.
For my understanding, the PG_STAT and VBUS_STAT will be changed until BQ25890H fulfill the above conditions, however, if VBUS=3.9V, can BQ25890H fulfill all the conditions? If not, what is the min voltage to fulfill the…
Part Number: BQ25890H Tool/software: Hi team,
In BQ25890H datasheet, I noticed there is a optional function D+ D- switch between charge and Host, I want to know is this necessary for tablet application? and which application is it necessary for? and…
Part Number: BQ25890H Other Parts Discussed in Thread: BQ25890 , BQ2970 , BQ25620 , , BQ25638 Tool/software: Dear TI Team,
We are currently utilizing the following ICs in our project:
BQ25890 for charging
BQ27621 for fuel gauging
BQ2970 for battery pro…
Part Number: BQ25890H Tool/software: Hi team，
can the ILIM pin NC in the real application? or it must to be connected to GND when not use? and I found When the charge is NC to system and battery, the input current, leakage current is about 20mA when NC…
Part Number: BQ25890H Other Parts Discussed in Thread: BQ25890 , Tool/software: The differences on the BQ25890H compared to the BQ25890 are as follows.
At startup in charge mode the H version not only does regular D+/D- detection the same as BQ25890,…
Part Number: BQ25890H Tool/software: Hi Team,
we're using ILIM resistor 260 ohm to limit the input current 1.5A. it is just followed example of datasheet.
when I calculated with provided formula 9.2.12 since we enabled ILIM pin, charging current…
Part Number: BQ25890H Tool/software: Hi team,my customer use bq25890H in their 1s battery tablet project. and they found the charge can't charge after battery is over discharged. In this time, Vbus=9V,and charge current=50mA, but the battery voltage…
Part Number: BQ25890H Other Parts Discussed in Thread: BQ27220 Tool/software: Hi Team,
recently we added a ferrite bead which has 220 ohm impedance @ 100Mhz band.
we placed it right before the VBUS trace, but there is a symptom that bead added board…
Part Number: BQ25890 Hi team,
I want to check the difference between BQ25890 and BQ25890H,
I have seen the HW differences in https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/686336/bq25890-bq25890-and-bq25890…
