Hello Christoph,
There is currently not a core off the self with a slot that fits the DRV421 Evaluation Module. I can help you with the design of the magnetic core and go over your design considerations to meet you needs.
Other Parts Discussed in Thread: DRV421EVM , DRV421 Hi,
I observed two problems during testing of DRV421EVM.
1) As shown in below figure if I connect let say S2 (in kit) to CL2 (compensation coil over core) and S1 to CL1, board takes 10mA while on interchanging…
Hello CSC,
The instability could change more than the offset as this is a closed loop system it could start oscillating and give invalid results. This can change with temperature or vary from device to device. I placed some documents below and highlighted…
Hello Mohamed,
All we have is the DRV421EVM that you can order. This does not include the compensation coil but it does have a Shunt resistor that may need to be adjusted for you current levels.
