Line-up of Hall elements

We offer a range of Hall elements featuring a variety of materials and package compositions to meet different customer requirements. Use the following procedure to select the Hall element that best suit your application.

Mode of use for application of Hall element

- Use as a switch.
Ultra-high sensitivity due to the use of magnetic concentrating material.

- Principal applications

DC brushless motors
Electric current sensors ( balance type)
Various switches
(Please prepare the switching circuit separately.)

- Use in analog output
V_Η changes linear with the magnetic flux density.

- Principal applications

Various analog position sensing
Electric current sensors (open type)

HW series

HQ series
HZ series
HG series

Selection of package

Comparison between HQ, HZ and HG series

In the case of constant voltage drive

	Hall output voltage V_Η (mV/3V, 50 mT)	Offset voltage ratio Vos/V_Η(*) (B=0/50mT)	Temperature coefficient of V_Η (%/°C)
HQ series	90 to 130	<6%	-0.2
HZ series	44 to 66	<16%	-0.14
High sensitivity HG series	39 to 51	<10%	-0.2
Normal sensitivity HG series (HG-106A)	33 to 42	<20%	-0.2
Normal sensitivity HG series (HG-106C)	28 to 33	<20%	-0.2

(*)Normal sensitivity HG and HZ series are converted because they are specified by the offset voltage.

Constant voltage drive

Constant voltage V<sub>Η</sub> thermal characteristics of various Hall elements

Constant current drive

	Hall output voltage V_Η (mV/1mA.50mT)	Offset voltage ratio Vos/V_Η(*) (B=0/50mT)	Temperature coefficient of V_Η (%/°C)
HQ series	Approx. 35	<6%	-0.4
High sensitivity HG series	Approx. 20	<10%	-0.04
Normal sensitivity HG series	Approx. 8	<20%	-0.025
HZ series	Approx. 5	<16%	-0.1

(*)Normal sensitivity HG and HZ series are converted because they are specified by the offset voltage.
(**)Because the output voltage in the constant current drive is not specified, it is stated as an approximate value.
