According to SAEJ2716 Rev. 4, HAR 379x of new sensor of effect of double chip suddenly Er accompanies PWM output and SENT agreement
Enclose with the SOIC8 of small size, measure function and functional redundancy to ask to safety severe exacting car and industrial application offer outstanding point of view
We will pass feeling and test to exhibit a hall in German Nuremberg at coming 28 days on June 26, 2018 204 exhibit on reveal HAR 379x
On June 7, 2018
TDK company expanded with HAR 379x range of products of sensor of effect of suddenly Er of Micronas double chip, the car that regulation of according to ISO 26262 is safe requirement severe exacting and industrial application are offerred multidimensional magnetic field measures a function. This one new sensor offers digital output: Besides wide modulation of arteries and veins (beyond PWM) , return the SAEJ2716 (rev with newest according to. 4) supports SENT agreement. The double chip SMD that HAR 379x is HAC 37xy range of products encloses version, used technology of Micronas 3D HAL® , 0°Measure point of view to 360° (the axis is carried and by axis all but) , linear displacement and position. Sample can be offerred since July 2018, 2019 the quantity is produced first quarter.
TDK general passes feeling and test to exhibit a hall in German Nuremberg at coming 28 days on June 26, 2018 204 exhibit on reveal HAR 379x.
The process designing character of diversity of HAR 379x sensor and pinpoint accuracy make its are become shift gear ideal system program of application, provide magnetic field intensity and angle signal. These two parameter can be obtained quickly through SENT interface. Additional, signal of magnetic field intensity can reach the Push function sex of the requirement. The product is ideal the circumstance that applies to need to measure linear displacement, for instance double separation and reunion measures footplate place in transmission application, regard engine journey as sensor, or position of cylinder body valve is measured.
Every HAR 379x has the chip of two substantive works, mutual on machinery and electron space. Because technology is advanced, the space between two inductions body is very little. The advantage is two Huoer component response is same a magnetic field, signal synchronism output has safeguard. In individual redundant design was placed to reduce systematic cost in enclosing, because reduced the pin on PCB,solder at the same time and enhanced systematic stability. Of HAR 379x enclosing is small size the SOIC8 of 8 feet.
Technique of traditional two dimension suddenly Er can the induction is perpendicular the magnetic field at chip surface. Micronas developed 3D HAL®Technology, will perpendicular Huo Er piece compositive make Cheng to standard CMOS in, from perpendicular with the level magnetic field of the induction on two direction, realized outstanding angle to measure a function. The HAR 379x of double chip is compositive redundant function. Every sensor includes a “ to resemble element unit ” , have a reaction two perpendicular direction (BX, BY) and way of a standard (the Huo Er of BZ) piece, contain the electric current on XYZ direction to compensate. Perpendicular Huo Er piece the induction is parallel the lines of force at sensor surface, the Huo Er with sensor surface parallel piece inductive perpendicular lines of force. HAR 379x comes true with low cost accurate lustre fine, and stability is behaved in bigger temperature limits. Sensor still contains signal processor to calculate and coordinate protection of inductor of two magnetic field, sensor, PWM and SAEJ2716 SENT output to wait for signal.
3D HAL®(Three-dimensional Huo Er) technology: Can be in a bit (resemble element unit namely) feeling measure X, Y, Z3 directional magnetic field
Explore the car application of rotational angle, for instance knob shifts gear implement (belt by press functional) , rear axle turns to a system
Feeling measure for example the linear position of system of clutch or brake pedal, transmission, cylinder body and valve position
Major attribute and advantage
±1.2° of error of the angle in intensity of 30 MT magnetic field
Axial end and by 360° angle measures the axis
Measure magnetic field directly (BX, BY, BZ)
Through SENT swift passage transmits angle and intensity information
The number outputs a format (PWM and SENT SAE J2716 Rev. 2016)
Apply to the application of high safe demand, ISO 26262 closes compasses
Double chip is offerred completely redundant
Temperature limits from – 40 °C arrives 150 °C, suit car application
