Part Number: DRV425 Other Parts Discussed in Thread: DRV401 Hi, is it possible or reasonable to measure current in the range of 1-10mA with Fluxgate-Sensors (DRV4xx) ? EB
Other Parts Discussed in Thread: DRV401 , OPA2350 hi everyone!
good day!
I saw in Design Drive kit IT used flux gate current sensor module which has 0~5 volt and it is so simple to convert it to 0~3.3v
how about -15v ad +15 which most of flux…
Part Number: DRV421 Other Parts Discussed in Thread: DRV401 1, what is the difference between DRV421 and DRV401 in application? Is the current range that the two can detect the same? The circuit designed by our existing DRV401 can detect 1A. If the detection…
Hi Brice,
In a 75kW system at 600V, the maximum current you should see will be 125A, so a ~1.5mΩ resistor should be sufficient to measure the current. This would be less than 0.2V of drop across the resistor or 25W. This is the maximum value, I expect…
Kura-san,
If they use DRV401 with INA826, I would expect the shunt resistor to be in front of the DRV401 and INA826 is being used to gain the signal coming out of DRV401. Therefore, in order to answer your question, I need to understand the circuit.…
Hello Brian,
The DRV425 is a open loop if you consider current (primary current you are measuring) as something that closes the loop. It does close the loop internally for the magnetic field. The DRV421 is more of a close loop system for measuring current…

모든 전기 시스템에 중요한 한 가지 중요한 매개변수는 전류다. 전기차 충전 및 태양 에너지 시스템은 전력 변환, 충전 및 방전을 제어 및 모니터링하기 위해 전류량을 감지할 필요가 있다. 전류 센서는 션트 저항에 걸친 전압 강하 또는 도체를 따라 흐르는 전류로 발생하는 자기장을 모니터링하여…
Part Number: DRV421 Other Parts Discussed in Thread: DRV401 I found DRV421 demagnetization is different from DRV401, the waveform of VIcomp in DRV401 is invariable, it doesn't change with the demag current .
when the demag current is large (Rshunt is…
Other Parts Discussed in Thread: DRV421 , DRV401 Hi Sir:
I want to know the DRV421 Or DRV401 When I use detect small signal current<= 30mA (AC or DC)How much detection accuracy can be achieved.
For AC What is the signal frequency range?
Part Number: DRV421 Other Parts Discussed in Thread: DRV401 , I have the following questions about fluxgate current sensor modulation chip, please refer to, thank you!
1, the following figure "parameter list" DRV401 can be applied to 1A primary rated…
