Part Number: BQ25672 Hi
The customer design with BQ25672, the charging setting is 1600mA, the battery is 2S, and the normal charging current for external 12V charging is about 1200mA. Currently, the highest charging current is found to be about 12V700mA…
Part Number: BQ25672 Hello team,
If Vbat is set to 16.8V, will SW2 voltage be 16.8V? If yes, how can we expect voltage drop at SYS pin and BAT pin?
Also, when Buck mode, is Q4 always ON or does current bypass body diode? If Q4 is ON, Vsys becomes 16.8V…
Part Number: BQ25672 Hello TI team.
I have several questions about a design I am working on using BQ25672 for power distribution for an IOT solution.
1) I want to use Vsys to power the controlling MCU and a GSM/GPRS module. The maximum Vsys_min of BQ25672…
Part Number: BQ25672 Hi Jeff,
Because the device is powered by DC 12V adapter, there is no use of USB d+d-. Please tell me how to deal with the d+d- pin without USB, and then how to deal with the useless QON pin,such as hanging?
Is there any other temperature…
Part Number: BQ25672 Hello team,
My customer is asking about how to terminate unused pins.
Do you advise below unused pins?
Pin 6 : D+
Pin 7 : D-
Pin 12 : QON
Pin 16 : TS
Pin 24 : SDRV
Pin 25 : SYS
Best Regards,

Part Number: BQ25672 I am working on a design that uses the BQ25672.
It is a 1S battery architecture.
According to the datasheet the Vsys output will be 3.5V to 4.1V.
My question is what is the max load current I can expect on the Vsys output?
I think…
