Is committed to providing differentiated semiconductor technology solutions in power, safety, reliability and performance leading supplier Microsemi Company (Microsemi Corporation) announced the launch of a new sensor interface IC-based sensing sensing technology (IC) first in a series device LX3301A, is the first use of the product on the market inductive sensor IC linear variable differential transformer (LVDT) on the printed circuit board (PCB) architecture implementation, designed for automotive application and industrial markets.
Almost all of the sensor is a key component in the feedback loop of a closed loop system, based on the characteristics of the LVDT principle using LX3301A sensor interface IC Microsemi inductive sensing technology, bring excellent anti-noise and interference. Microsemi the art can also replace prevailing Hall effect (Hall-effect) sensor on the market, these vulnerable to an external magnetic field and / or affected by metal objects near the magnet-based sensor; however, this technology eliminates sensor magnet , so as to enhance the immunity to this type of interference.
Vice president of US high Sammy and business unit managers ShafyEltoukhy said: "Microsemi is a leader in inductive sensing technology, more than five years has been providing custom IC production of products, we are pleased LX3301A expand market opportunities inductive sensing is one. item may replace the Hall effect sensor in a wide range of mechanical motion sensing applications of emerging technologies, and to provide a significant improve temperature stability, enhanced reliability and security, and lower system cost. "
The new device is suitable for various applications associated with the industrial automation and control systems, especially linear displacement measurements (fluid level sensor, the gear position of the transmission actuator position, brake light switch / proximity detector) and measured angular motion (robot arm position, the position of the rotary shaft, and rotation control pedal position). The device also meets the stringent requirements of automotive applications, including AECQ100 level 1 certification, ISO26262 file support compliance and Production Part Approval Process (PPAP).
Additional features include:
Non-contact sensor (high reliability)
12kB program memory having an embedded 32-bit processing engine
2 having an integrated sensor input channel demodulator
Having from 1 to 5 MHz in the frequency range of the internal oscillator
ADC 13 having double the sampling rate of 2kHz
16x16-bit user-programmable non-volatile configuration memory
By experienced automotive technical support team to ensure the successful application of customer
Sensor continues growing popularity throughout the automotive and industrial markets, such as "MEMS Journal" magazine pointed out that worldwide Shipping new light-duty vehicles (cars and light trucks) in 2014 will grow from about 85 million to 100 million in 2020. 1000 million, currently has an average of these vehicles per 60-100 sensors, but with the "intelligence" of the car to improve quickly, estimate that the number of sensors per vehicle will reach 200, in other words, to 2020, the automobile industry uses about 22 billion sensors per year.
LX33xx sensor IC may be used in series Microsemi motor driving reference design, SmartFusion®2 system on chip (SoC) field programmable gate array (FPGA) and a motor control IP suite to process the sensor inputs and the motor driving algorithm.
