Part Number: BQ77915 Hi Team,
Could you help our customer's concern.
I have a question regarding the BQ77915 BMS chip. its about a design circuit shown in the documentation.
Under what circumstances would the transistor highlighted in…
the switch node shows negative spike of -4V and the limit is -1V. The positive spikes at switching is 21V and the limit is 30V. I would like to see the LDRV2 signal pin 23 by itself. I want to see if the 2V during off time. If it is real, there…
Part Number: LM27761 Hi TI
I am preparing use LM27761DSGT to design LDO circuit, so I have some question about LM27761DSGT:
1. LM27761DSGT first use a charge pump convert Vin to -Vin, and then use a LDO convert -Vin to Vout?
2. In my design, Vin=3.3V…
Part Number: TPS23755 Hi Sir,
My customer use TPS23755 in their IPCAM design. They finished their design and shipped products to end customer already. But There're high rate field returned from end customer in bus cam application. Would you please helping…
Other Parts Discussed in Thread: TPS3431 Hello Team,
We have following ICs used in our sensor based project having gateway application.Can you please help me by reviewing schematic designs for all TI parts we have used.
Tri Chau said: 1. What is the function of the lower left part of the design (with question mark)? I don't see how the voltage put across the load is the same as the AC source.
C1 and R7 is your biophysical sample. I have assumed for R7 a range…
Hi Quang Luu,
Your layout placement is good.
The output capacitors placement is good too.
The feedback resistor placement is not good. The lower feedback resistor R61 should be right next to FB pin and AGND pin. Consider using smaller footprint components…
Sorry for the delay, I have finished the review please see my comments below.
1. It looks like the 1.1V power supply is labeled as 1V2. Can you confirm this is meant to be 1.1V?
2. It appears that you are missing a 0.01uF cap for each pin.
