Dear, Sir.
My customer is considering to realize the measureing DC +/- 400 ~ 600A.
It looks possible to refer TIPD205.
Could you please teach us several things because we are not familiar with this product.
1. DRV425 Fluxgate.
a) I have a chance to see the pronciple of Fluxgatre, before.
It was configured eith Excitation, Sensing, Compensation coils & 2 magnetic cores
(Non-inverting, Inverting).
I wonder DRV425 is integrated such portion inside of IC?
2. TIPD205.
It is mounted 2 pcs of DRV425 to measure the absolute position, and show as Voffset.
b) I wonder the influence of geomagnetic & adjacent field will be observed on Voffset?
c) I wonder DRV425 is just measuring above, So will not do automatic correction, it will
be done by external MCU to capture the signal through ADC?
D) Is it possible to realize +/- 100A DC current sense using just 1 DRV425?
If yes, Please let us know the bottle-neck to realize that(for instance, accuracy got
worse than the case of 2 DRV425 because the current unbalance on right/left side
of hole could not be involved, etc).
Best Regards,
H. Sakai
