Part Number: INA3221 Other Parts Discussed in Thread: INA4230 , INA226 , INA4235 Hello,
I have an application where I am running a long set of wires to this voltage monitor, containing two INA3221 chips using addresses 0x40 and 0x41. The I2C interface…
Part Number: INA3221
We are using INA3221 for voltage and current measurement on three channels.
How the following four alert pins are related to three channels.
Critical (9), Warning (8), PV (10), TC (13).
The threshold for Critical (9), Warning…
Part Number: INA3221 Tool/software: Hi expert,
Want to confirm how should customer connect the unused channel?
For example, CH1 is the unused channel, connect the unused CH1 IN- to either used CH2 IN- or CH3 IN- is fine. And float the unused CH1 IN…
Part Number: INA3221 Tool/software: HI Team,
About INA3221 the datasheet show it's has 3 ch and 1 ADC with mux function.
If ADC switch to ch 1 and in this moment other ch occur critical or warning event.
Does the alert will be issued?
Or alert…

Part Number: INA3221 Other Parts Discussed in Thread: INA4230 , INA4235 Tool/software: Hello,
I would like to know INA3221 effective shunt voltage resolution including error factor of VOS, DNL, INL.
With considering VOS +/-80uV, the effective resolution…
Part Number: INA3221 Hi Team,
Customer have 2 questions about INA3221.
1. What's the Vgsth of PV open-drain output MOSFET?
2. What's the output type of Power valid detection? Vpu used as push-pull power supply or pull up of another open-drain…
Part Number: INA3221 Tool/software: Hi team,
The customer wants to detect 6 groups of current on the board. Use two INA3221s, both power supply voltages are +12V Have the following questions 1. Does INA3221 need to write a default code? 2. What is the…
Part Number: INA3221 Other Parts Discussed in Thread: SYSCONFIG , INA4235 Tool/software: Hello, I am using INA3221 Ic to get the shunt current and bus voltage, I have tried this application at many different loads and voltage level & current levels. But…
Part Number: INA3221 Hi,
I'm using INA3221AIRGVR in my R&D project with all 3 channels connected as following:
- CH1 -> track 5V
- CH2 -> track 1.8V
- CH3 -> track 3.3V
1. For VPU, I connected it to VS (3.3V). Therefore, can PV (Power Valid…
