Part Number: INA229 Hello, I've noticed an issue where occasionally the INA229 starts sending invalid / unexpected data on MISO back to the STM32 main micro. This usually happens when the micro (not INA229) is soft reset or power cycled. After this occurs…
Part Number: INA229 I want to drive the current measurement time down from what I am seeing from a single ina229, which yields acceptable performance at longest conversion time (~4 msec) with 16 samples averaged.
I’m considering an alternate design where…

Hi all,
I would like ask you about INA229. I bought 10pcs from Digikey but I have problems with communication via SPI. INA229 still do not response from any register. I tried change speed, I also changed IC 3 times without any progress…

Hello everyone,
I am using an INA229 to read Shunt Voltage and Current. It is configured to have a 40,96mV maximum Shunt Voltage.
I'm using a 2,7Ohm resistor as Shunt Resistor and expecting a 15mA maximum Shunt Current (40,96mV/2…
Part Number: INA229 Other Parts Discussed in Thread: INA223 Hi expert,
Customer needs power meter IC to be embedded in their ACDC power supply product to measure the power supply's input power and PF, like a power meter feature. I only thought of TI's…
Part Number: INA229 I want to control INA229 and another device using one SPI. (Of course, it is assumed that the basic settings (CPOL, CPHA, etc.) are the same.) However, when MISO of INA229 and another device (here AD5270 of analog device) is shared,…
Part Number: INA229-Q1 Other Parts Discussed in Thread: INA229 Hi,
I use the INA229 to monitor the current in a battery powered system.
From time to time, the current reading becomes wrong, with different behaviours from one failure to the other (small…
Hello Hangjie,
Here are my responses to your questions:
Hangjie Wang said: And you mentioned that the default configuration is the maximum or minimum value, and this is the root cause of the inability to trigger the protection. Can this be equivalent to…
