how to interface current sensor with psoc

[Anonymous]

nstead of acs714 i am using wcs2750.i have attached data sheet of it.how to interface this with psoc??i have written the code already but problem with interfacing.is there any current sensor other than this??

What difficulties do you exactly have? I would start from here.

This part has a nominal 2.6 Vdc @ a current of 0 A, and a sensitivity of

   

32 mV/A nominal. So max Vout = 2.6 + ( .032 x 60 ) = 4.52 V. Note the min

   

Vout = 2.6 - ( .032 x 60 ) = .68. All nominal.

       

So Imeas = .032 x Vout + 2.6 ( This is your equation to calc current measured)

       

Using Vssa to Vdda as range setting for ADC, ADC buffer gain = 1,

   

should accomplish what you need.

        Hi, This Hall sensor have a pre-process for sensing voltage, You would be good to use simple ADC. One thing I have to add, At the circumstance for the strong current sensing thats temperature is hot. It looks -30%, You might consider about that, If you needed, It's a good to a temperature correction by PSoC. And that mean need more one ADC for the temperature sensing. Thank you.

The sensor shows a T compensation block, and spec shows a drift of

   

.5 mV/C. But spec incomplete.

       

One A/.D with a mux will serve if you need external Tsense, but you will

   

have to get characterization data on T performance from vendor as there

   

is none in datasheet.

       

All depends on your absolute accuracy and linearity requirments, none addressed

   

in datasheet.
