Hi, I'm using some VNQ5E160AK with current monitoring. According to datasheet Iout/Isense ratio is in the range of 465 for 'high' current, means it should be 6.5mA for 3A and 21.5mA for 10A. As my ADC range is 5V, I load sense pin with a 200 Ohm resi...

Hi gent'ssorry: my first post here, hope everything goes well.I would like to redesign an antenna for an 95HF, today for test, we use a Nucleo board and it's working pretty well; but I think we can do better.We need to read 2 tags: one on the Wafer P...

Well, find answer my self reading UM1556: Isense is internally limited to about 11mA by M1, so "no way" to get 21.5mA for 10A. In fact, if you assume a K factor of 465, you won't be able to monitor a current higher than 5.1A ! doesn't matter what you...
