Part Number: INA233
How to use the power accumulator
The INA233 has a power accumulator built into the device, which records the sum of the power measurements, number of measurements, and number of times the sum register has rolled over.
Here's how the part works, from single measurement to accumulated power:
Dividing the power accumulator by the sample count gives an average energy used for the monitored time period. A common question about the power accumulator is about how much time can power measurements be taken before the energy accumulator overflows? The answer depends on a number of factors -
The following excel worksheet can help calculate how long the INA233 can sample before overflow occurs in the Power Accumulator. Understand that it is based on average expected power and not maximum power. If your system operates at maximum power for a long period of time, it can fill the accumulator much more quickly than anticipated. If you are concerned with this, make the Expected Average Current and Peak Current fields the same.
