Hello Ajay,
Until you provide the details that Javier is asking for, we have no information to troubleshoot your circuit. I am going to change the status of this thread to waiting for customer as we cannot troubleshoot in the dark.
Please provide the…
Part Number: DRV421 Hello All
- We are working with DRV421. Looking to the user manual, ER asserts low when having a demagnetization cycle.
- We have performed some measurement monitoring OR and ER pin. In the below scope screenshot, in yellow is OR pin…
Part Number: DRV421 Hello technical team,
I want to implement a circuit based on DRV421 for closed loop application. I want to know the parameters of the coil integrated internally in the DRV421.
Part Number: DRV421 Other Parts Discussed in Thread: DRV411 , TIPD184 Hi Support team,
do you have a simulation model for DRV421? It would be great for LTspice. If not, could you tell me how I can simulation the output signal of Icomp1 and Icomp2? I tried…
Part Number: DRV421 Hello E2E Experts,
Good day.
We are in the late stage of the development of a Residual Current Monitoring device (IEC62752 compliant) using the DRV421 IC. Recently, we performed high-low temperature tests on the device and discovered…
Part Number: DRV421 Hello. DRV421 can be used aven in +/-15V applications (datasheet point 8.2.3).
However an external driver is nesessary because of the limits of the chip. What driver do you suggest? I suppose operational amplifier followed by npn+pnp…
Part Number: DRV421 Hello
I'm designing a current sensor using the DRV421that seems to work very well
My question is : if I have only to measure positive currents what is the best way to get a 0/5V signal (0V-->Imin=0Ampere 5-->Imax)?
Should…
Part Number: DRV421 Hi,
My customer need assistance.
This is an application case where I use DRV421 for a closed-loop current sensor. The circuit diagram is shown in the figure.

The product can output the current value normally…
Part Number: DRV421 Hello,
We are developing a current sensor based on the DRV421. Right now, we are having issues with the magnetic shield. We noted that after adding the shielding the sensor started to act erratically. Then, we realized that this happens…
