Part Number: BQ24172 Tool/software: I am using the BQ24172 and have a few questions. Regarding the graph in Figure 13 on page 13 of the BQ24172 datasheet, is there any data available for when the Charge Current is below 0.5A with VIN set to 5V? Additionally…
Part Number: BQ24172 HI
I HAVE A CIRCUIT WITH BQ24172 AS CHARGER & ACFET& RBFET P.N CDS17309Q3.
I have designed this board mainly based on BQ24172EVM-706-15V board .
I HAVE NOTICED THAT 30% OF THE MANUFACTURED CARDS HAVE A PROBLEM OF POWER THAT…
Part Number: BQ24172 Hello,
If I want to disable the DPM function for bq24172, may I do it like the red remarks, which I did in the screenshot as below?
1) Replace RAC with a short, remove C11;
2)Remove R4 and R5, and connect VACSET to VREF. …
Part Number: BQ24172 We are using Bq24172 as our charger.
We noticed that when VBAT < 5.8V, and we plug adaptor (15V) for charging, we saw Vsys will drop from 5.8V to 5.0V, then pull up to adaptor voltage 15V.
Is there any possibile reason for this…
Part Number: BQ24172 Hi,
The below image is our schematic design
Here, we are giving 12V input to the power connector. when I checked voltage after Q6(ACFET),voltage is 6V. Why 12V is reduced to 6V?
Please help me resolve this.
Part Number: BQ24172 Hi ,
Im using BQ24172 charger to charge two 3.7V batteries connected in parallel. The battery charging voltage is 4.2v and the charging current is set to 1A.
In this setting, will BQ24172 charge the batteries with charging current…
Part Number: BQ24172 Hi,
In our design, BQ24172 will be used to charge a battery with ISET = 2A and VBATT= 4.2V. Adaptor input voltage will be 12V and load will take around 1A. Please tell me with this configuration, how current will BQ24172 take to…
Part Number: BQ24172 In reference to the BQ24172 Lipo charger IC.
How important are the external Schottky diodes on the “SW” and “BTST” pins? Data sheet gives no guidance as to when these are needed.
Efficiency should improve with the proper external…
