Part Number: INA3221 Tool/software: Hi Team,
I am using the current sensor part INA3221AIRGVR in my design. I want to know the way to select power rating of the sense resistor, that we are using for this. Where can I get this guideline? The maximum current…
Part Number: INA3221-Q1 Other Parts Discussed in Thread: INA4230 , INA4235 , INA3221 Tool/software: hi TI expert,
we meet a issue , that is we designe INA3221-Q1 I2C addr as 0X42 ( connect A0 to SDA), but sometimes we could not i2cscan 0x42 but 0x43(sometimes…
Part Number: INA3221 Tool/software: With the AVG bits set to 0x7, VbusCT bits set to 0x7, and VshuntCT bits set to 0x7, am I correct in stating that it would take ~50.6 seconds for the chip to read the shunt and bus for all 3 channels?
(8.244ms[VbusCT…
Part Number: INA3221 Other Parts Discussed in Thread: INA296A , INA226 , ISO1643 Tool/software: I am wondering if possible to use INA3221 for monitoring bus and shunt voltage on a negative rail. The negative rail is -5 V supplied by the linear regulator…
Hello John,
John B said: I am wondering how can I find from datasheet that t he Vbus Impedance is 670kΩ ?
Yes, you found the right spot. It's spec'd a little different in this datasheet than we usually spec it, but that is the location. The VBUS is measured…
