Configurable type solid solution for field sensor strict linear IC application

雷竞技竞猜下载Allegro MicroSystems, LLC announced the launch of new high precision programmable linear hall effect sensor IC productsA1342, the integrated circuit has open drain output, suitable for automotive and other applications.Through external programming, Allegro company A1342 device can provide very high flexibility, the signal path allows accurate magnetic signal generated from the input and the output of the custom.

New devices are for the most demanding linear field sensor IC and specially configured application robust solutions.The BiCMOS, monolithic IC integrated hall sensors and precision temperature compensation circuit, can reduce the inherent sensitivity of hall element and zero drift.The device also integrated with proprietary dynamic offset to eliminate small signal, high gain amplifier circuit, advanced output linear circuit and the advanced diagnosis function, can provide unparalleled customer programmable options.

A1342 device is one of the key features of can for non-linear input magnetic field can generate high linear output device.To this end, the calibration field devices with 16 - to segment customers, which are unique to each section can be used linearization coefficient factor (linearization coefficient factor).Linearized coefficient block is stored in the EEPROM in the lookup table.

The new device has two configurable output options: SENT or PWM.Besides SAEJ2716, this IC including proprietary SENT two additional options: SSENT and ASENT, both protocols can make the bus in a SENT on a line configuration as many as four parts, to reduce the system cost.SSENT can provide sequential access for sensors of the same line connection, it is a very economic and effective method, can maximize the single root SENT online sensor bandwidth, to reduce the impact on system performance.And ASENT can random access the same SENT all the sensors on the line.The two agreement to allow each sensor on the same line into diagnosis mode, while the other sensors continue to respond to inquiries, so as to realize the highest diagnostic coverage, at the same time maintain 100% sensor solutions available.

A1342 device adopts single straight hole lead-free 3 pin plug type package (SIP) (UC suffix), fog lead frame with 100% of tin plating.UC package includes the integration capacitor for ESD to improve performance and achieve no PCB - less (PCB) design.
