We are going to build a PCB with a custom ASIC on it and I'd like to measure it's (ASIC) power consumption during the operation
time. I know the easiest way would be just "connect Lab equipment to your PCB the record whatever you wish", but I was thinking (for
the demonstration purposes) to have a dedicated IC on board, which will sense current and provide the power consumption of the ASIC at the output.
Can you recommend any of your SoC for this purpuse?
On the webside I found some threads saying that it's possible to use ADE energy meters measure DC, by disebling some HPFs, however most of them are for AC and for high voltages. We will have a DC device, which supply voltage can go down to 0V5 with 100s of mA currents.
Yes. You can use an ADE IC for your application and I will be able to help you select one. You will need to use a shunt resistor as current sensor. Can you answer some questions for me so that…
I have some suggestions for you:
1. I would encourage you to post your questions on other communities such as Power By Linear and Amplifiers, where someone might help you find a product more on…
the ADM1293 recently released or ADM1192 do exactly what you want, they measures current, voltage power and energy for a DC type system.
We have a few parts in this family some with better accuracy than others and all come with a software that can be used in a demo environment through a USB connection. Some of the parts may be called Hot Swap because they have an additional funtion to limit current during start up bu they all have at least the current monitioring capability.
Here is a sample of some of the other devices:
