FAQ and answers about hall effect IC

Hall effect IC common

	Q1	Where is the sensor location in the package?
	A1	For the location viewed from the sensor top, refer to the pdf file for each grade. For the depth from the marked surface, click here.
	Q2	Which output is present at power on, H or L?
	A2	When the magnetic flux density is Bop or higher, it is L. When it is Brp or lower, it is H. When it is between Bop and Brp, it varies.
	Q3	What kind of plating is applied to the lead terminals in the hall effect IC?
	A3	The EW-5 series is palladium plated. All others are tin plated and comply with RoHS. (As of April 2007)

EW series (excluding EW-6671, 6672, 6771, and 7671 that are driven by hall element pulses)

	Q1	How fast the response speed (the duration from the magnetic flux density exceeds Bop to the time when the output changes) is?
	A1	It depends on the grade, but roughly estimated, it is 5 μs or less.

EM series and EW-6671, 6672, 6771, and 7671

	Q1	Shall the bypass capacitor be installed?
	A1	Install in principle.
	Q2	What is the difference between EM-0711 (EM-1711) and EM-0712 (EM-1712)?
	A2	When PDN = H, in EM-0711 (EM-1711), the hall element drives continuously, but in EM-0712 (EM-1712), the pulse drive turns on. Therefore, EM-0712 (EM-1712) has smaller consumed current.
