Specially designed for safety critical car application

Worcester, Massachusetts- 亚博棋牌游戏Allegro MicroSystems, LLC, a new series is suitable for high speed motor position sensing of contactless magnetic hall effect sensor IC.Allegro 'sA1331andA1334Double Angle sensor chip IC based on the vertical technology of hall effect.Used on a chip (SoC) system architecture A1331 and A1334 can provide fast refresh rate and low signal path delay, in order to meet all kinds of automotive and industrial applications of demanding requirements.Two kinds of device can meet the requirements of automotive applications, such as electric power steering system (EPS), dynamic braking motor position sensor, actuator/actuator position sensor, throttle pedal position detection, and other needs accurate measurement of Angle position and rotational position system.

A1331 and A1334 IC chip IC provided the TSSOP - 24 packaging, the packaging contains two separate cutting silicon IC, electrical isolation.These two IC chip is suitable for the safety in redundant sensor IC will be used to use critical application environment, especially to meet the requirements of ASIL systems.

A1331 and A1334 onboard digital signal processing function and block the EEPROM programmable functions for factories and customers, they are particularly suitable for need super fast refresh rate and low output signal path delay axis/shaft end applications.These IC line 4-10 MHz SPI interface provides 25 (including s output refresh rate, nominal signal path delay is only (including 60 s.In addition, the IC can run directly depend on the automobile storage battery, and support the power supply voltage of 4.5 V to 14.5 V, and each wafer consumes only current of 10 mA (Max).These dual chip IC also contains the signal path and the I/O diagnostic device, which can meet the strict ASIL safety requirements.

Both devices can run at low RPM mode, to support the top 12 bits output resolution, they also can run at higher RPM mode, to support the need for faster refresh rate and lower the application of single path delay.As part of its function of signal processing, IC has auto temperature compensation function, in the whole operating temperature range of the device (to 40 ° C to 150 ° C) and within the scope of voltage (4.5 V to 14.5 V) to provide accurate Angle measurement.A1331 and A1334 output signal in wide range of magnetic field and high precision, and can be more than in less than 300 G and 1000 G magnetic field within the scope of operation.Block on a chip EEPROM technology also gives users for flexible programming IC.

A1331 IC is unique in that it contains micropower operation mode and internal electronic turn counting function.These function in the application in automobile power steering (EPS) is very important, because it must be tracked multiple rotating absolute position of the steering wheel.When the car in A stall state ", "A1331 can connect the car battery, hand in hand to detail power operation mode (each chip consume an average of 100 including A).When is in micro power mode, A1331 will detect the rotation of the steering wheel, the steering wheel and induction and storing of revolution, even if the car in the off state.Therefore, when the car start (ignition), steering system can understand the absolute position of the steering wheel.Turn the counting function to 180 mechanical degrees of increment, and can is incremental in 511 and 512 negative increment within the scope of work.
