DRV421
Question / Description:
Hi TI E2E Team,
We are currently evaluating the DRV421 for a high-precision closed-loop fluxgate residual current sensor design, targeting industrial…
Part Number: DRV421 Hello,
I am regarding the feasability to design a current sensor with your DRV421.
I need to measure the current up to 100KHz. Can the DRV421 reach this frequency or higher?
What would be the best magnetic material to reach this…
Part Number: DRV421 Hi
Could you please advise if there is an official reference design using the DRV421 for the LEM LDSR 0.3-TP/SP1 ? Any technical documentation or design guidelines on this combination would be highly appreciated.

Part Number: DRV421 Tool/software: Hello, a separate E2E thread for this IC confirms this works for 400A current sensing: DRV421: DRV421 for 400A DC current - Sensors forum - Sensors - TI E2E support forums
However, this may not be the actual maximum…
Part Number: DRV421 Other Parts Discussed in Thread: DRV411 Tool/software: Hi everyone,
does anybody know in which case the optional schottky diodes are needed? And what is the purpose of this? If I use an external amplifier (supplied by +/-15V), then…
Part Number: DRV421 What is the output voltage range for DRV421? Is there any formula using which we can calculate the output voltage based on the input current? As per the datasheet, a formula is given but certain parameters such as the no of primary…
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 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…
