4.6. EMC and ESD

For applications that cause disturbances on the supply

line or radiated disturbances, a series resistor and a

capacitor are recommended (see Fig. 4–1). The series

resistor and the capacitor should be placed as closely

as possible to the Hall sensor.

Please contact Micronas for detailed investigation

reports with EMC and ESD results.
