1. What determines the number of probe turns connected to the chip? How to determine the number of probe coils?
2. Why does the modified width of the amorphous ribbon in the probe coil affect the frequency of the probe? Is there this formula?
3. How to…
Part Number: DRV401 Hi Staff,
on page 22 in the DRV401 data sheet, a filter stage at the N_PWM output is shown (R3,C3,R4,C4). What kind of filter do the components form and how to choose appropriate values?
Best regards
Joachim

Team,
In the datasheet we provide the below info about clamp diodes and the need to limit the input current:
What is the max and typ current that those protection on ICOMP1/ICOMP2 can sustain? What is the life time of this protection…
Part Number: DRV401 Other Parts Discussed in Thread: DRV425 Hi Team,
The customer wants to make a small size current sensor that can measure AC and DC to replace the current transformer. What is the accuracy of DRV401 and DRV425 in the full range of 100mA…
Part Number: DRV401 Hi:
I want to use vocuum to auto pick &place our PCBA product into packing trays.
Because the size problem, I only have to use the vocuum nozzle to pick the IC body.
Aim to the automation machine can pick the PCBA 100%, I need…
Part Number: DRV401 Hi, Staff
Large offset output
The current sensor using the DRV401 has been confirmed to operate in a manner that does not meet the device specifications.
An individual whose output (offset output) is large when the input current is…
Part Number: DRV401 Hello,
based on DRV401, i'd like to learn about what would have effects on oscilating frequency of fluxgate? magnitc core and winding? But how do they work?
And if the turns of fluxgate become more, the frequency is bigger or samller…
