AM437X: Isolated current shunt and voltage measurement

Other Parts Discussed in Thread: TIDA-00555, TIDA-00601, TIDA-00080

Hello,

I found this device on your website and was told it is not available for purchase. www.ti.com/.../tidu755.pdf

Are their any measurement devices similar to the tidu755 device listed above? I am developing a solar inverter prototype, and looking for a measurement device to interface with a DSP board and monitor AC voltage and Current and also DC voltage up to 1000VDC.

Please Help

Thank you

Hi Joe,
Your post is being moved to the Sitara forum for better support.

By the way, is there a specific device in the reference design that you are referencing?

Hi,

I'm not sure I understand the question. What are you looking for - a board to purchase or a reference design?

Rick,

Thanks for the quick response. And no, not a specific device. I am looking for a measurement board similar that can measure 3 phase voltage and current, and also the DC voltage.

I don't think there are any Sitara boards available to suit your requirements. TI offers only evaluation boards (EVM) for the Sitara processor family.

Joe,

Similar to TID-00290 (TIDU755) we have several TI Designs that showcase how to design Isolated current and voltage measurement sub-systems. You could also look at TIDA-00555, TIDA-00080 and TIDA-00601. However TI Desing is not available for purchase - they are intended to show customers how to design their systems using TI devices. Let us know if you have any further questions on designing an isolated V & I measurement sub-system.
