FH3D02 Overview 1 FH3D02 Overview 1.1 General Description The FH3D02 is a dual 3D magnetic field sensor using two 3D Hall sensors using the HallinOne® technology, which are also called “pixels”. The versatile magnetic field sensor is suited for measuring all magnetic field components in three dimensions. It can be used as a magnetic field probe or a position sensor for linear or rotary movement of permanent magnets. A variety of applications can be evaluated instantly with the standard programming.

Characteristics 2 Characteristics 2.1 Absolute Maximum Ratings Stresses beyond those listed here may cause permanent damage to the device. These are stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under “Operating Conditions” is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Parameter Min Max VDD Unit 5 V V Note Input pin voltage -0.3 VDD+0.

Package and Circuit Connection 3.2 Pins Pin Symbol Type A1 MISO DO_T A2 CLK A3 B3 VSS1 S A4 SCE DI_ST Test pin, must be connected to VSS in normal operation A5 LOPOW R DI_ST Shutdown & Reset input.
Package and Circuit Connection 3.3 Electrical Connection The sensor chip must be connected to a supply of 3.3V via its VDD and VSS pins. All unused pins should be connected to VSS to guarantee proper function. A decoupling capacitor between VDD and VSS close to the sensor chip is strongly recommended as well as the usage of non-magnetic components nearby to prevent magnetic interference.
