Technical Information
We offer a comprehensive range of Hall effect ICs to cater for different customer requirements.
The procedure for selecting the most appropriate Hall effect IC for your application is as follows:
Our Products may not meet your requirement. Please inquire for details.
The Hall effect IC consists of Hall element and signal conditioning circuitry to convert the Hall element output into a digital output. The two devices are mounted in a single package with three active terminals(Power, GND and output).There are two choices of power consumption. Continuous powered devices with standard current consumption and pulsed powered devices at low duty cycles that significantly reduce the average current consumption to microamps.
Two types of output circuit are available: open collector type and an internal pull-up resistor type. The open collector type Hall effect IC is generally used to connect an external resistor RL as shown in Figure 2.
The normal operating temperature for this type is -30°C to 115°C.
The Hall element is driven by the electric current pulse shown in Figure 4, and the output is as shown in Figure 5. As for output when it is not driven, the immediately preceding state is maintained. Usually, the period of the pulse drive is predetermined in each grade of Hall effect IC and cannot be externally controlled. The normal operating temperature range for this type is -30°C to 85°C.
On/off is switched depending on the intensity of the magnetic field of the S-pole of the magnet.
This type is primarily used for position detection of a magnet.
On/off is switched depending on the intensity of the magnetic field in S-pole or N-pole of the magnet. This type is primarily used for position detection of a magnet.(It is not dependent on the direction of the magnetic pole.)
On/off is switched when the magnetic fields at the N-pole and the S-pole are applied alternately. This type is primarily used to detect revolution speed.

FAQ
[A01] 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.
[A02] 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.
[A03] The EW-5 series is palladium plated. All others are tin plated and comply with RoHS. (As of April 2007)
[A01] It depends on the grade, but roughly estimated, it is 5 μs or less.
[A01] Install in principle.
[A02] When PDN = H, in EM-0711 (EM-1711), the hall element drives continuously, but in EM-1712, the pulse drive turns on. Therefore, EM-1712 has smaller consumed current.
