Thank you Upal.
After talking with my client, she wants to move forward with the higher power option. I realize you have a lot of options here and the comparison tool on TI isn't much help in understanding the difference so I'm hoping you can help clarify…
Hey Shi,
This part is not really adapted for standalone use. If you use the charger without i2c communication, all settings with be in their default state except for input current limit which you can only set lower than the default setting (based on…
Muthu,
The BQ24266 was made NRND because we have a new standalone charger, the BQ25606, to replace it. We have not yet NRND'd the BQ24253 because of its unique shipmode feature but it will likely be NRND'd in the near future. As a reminder, even though…
Hi Wyatt
Thanks for update. Let me brief you all experiments which we have done till now and not getting proper SOC with respect to fuel gauge voltage.\
1. Initially, we have done on Learning cycle on Fuel Gauge with four parameter as per datasheet…
Kaizawa-san,
The customer can certainly replace the EVM IC. Before we prepare an EVM, I would like to confirm that this is the best IC for the application. So can I get more information about the application, including end equipment, input voltage…
Hi Jeff,
A)What is the Vsys when the battery is fully charged ?
Our input power from USB is 15W (5V * 3A) , and from DC AUX is also 15W because the power mux a current limit on 3A.
B)then the max output power when the battery is discharged from…
Onyx,
Customer is using the BQ25898 battery charger
The BQ25606 battery charger
And the BQ27542 fuel gauge.
They have EVMs for each of the above devices.
Do they need the GDK to be able to run BQStudio with the above EVM’s?
The documentation seems…
PS:
Lowering the source to gate resistor of P mosfets from 100k to 10k (as recommended in bq25606 DS as maximum pull-up value on STAT and PGOOD pins) doesn't change anything: there still is a 7Hz STAT pin blinking when no battery is connected.
Thank…
Hello,
At default, the charge current on the bq24192 is set to 2048mA.
Since this is an I2C control register to configure charge current, this setting needs to be configured using an I2C host.
Two recommendations/questions:
1. Why must the host…
Hi CC,
The BQ25606 is my recommendation for the charging circuit. When powered from 5V, it will provide power to its SYS output (IC output above) with a minimum system voltage of ~3.7V and then starts following the battery voltage up to BATREG. The…
