Part Number: DRV425EVM Other Parts Discussed in Thread: DRV425 , DRV421 , TIPD205 I need to measure a DC current of 100 milliamps with the DRV425 EVM kit. I would like to know how this component works. I am not familiar with the concept of this product. …
Akash,
The DRV5053 sensitivity can easily drift 5% over temperature, The DRV5055 sensitivity can also drift (please Figures 3 and 4 in DRV5055 datasheet)., but the sensitivity thresholds are much tighter. For example, the DRV5053PA has typical sensitivity…
The are many ways to measure current and Texas Instruments has a diverse portfolio to do exactly that!
Here are a few links to get you started measuring current with TI products:
If you don't know where to start with your current measurement design,…
John,
Excuse me delay as I was on international travel. Please take the numbers below as a rough guide of the expected magnetic field. These numbers are like the 546uT at 100A in the TI Design http://www.ti.com/tool/TIPD205 in section 2. The placement of…
Charles,
I sincerely apologies for my over sight and delay.
Increasing Rshunt decreases range due to the fact that we are now increasing the gain of the circuit. When we have 12.2mA/mT and we increase the Rshunt then we are gaining up the voltage we are…
