Current Sensor ICs
Allegro MicroSystems, LLC has developed a line of fully integrated Hall-effect current sensor and Hall-effect linear integrated circuits that provide highly accurate, low noise output voltage signals that are proportional to an applied AC or DC current. These ICs are in high volume production in many applications, including automotive HEV inverters and electronic power steering (EPS) systems, and in industrial and consumer inverters and motor control applications.
Allegro current sensor ICs are also used in many power monitoring applications, such as computer blade servers and server power supplies. Allegro's proprietary fully integrated Hall-effect current sensor ICs employ advanced IC and packaging techniques for sensing current from 0 A to 50 A and 50 A to 200 A. These integrated solutions provide galvanic isolation (up to 4.8 kV) and extremely low resistance on the primary conductor (≤ 1m?) for highly efficient solutions and are available in a variety of surface mount and through-hole packages. For sensing beyond 200 A, an Allegro linear current sensor IC can be used.
Allegro current sensor ICs allow design engineers to use Hall-effect-based current sensor ICs in new applications where increased energy efficiency or new operating features are required.
Magnetic Digital Position Sensor ICs
Hall-effect digital position sensor ICs detect changes in magnetic flux density, allowing them to distinguish movement and position. These contactless sensing solutions require few external components and can withstand the hostile operating conditions of automotive applications. Allegro has the industry’s broadest portfolio of magnetic digital position sensors with switching and latching solutions to cover just about any application need.
Specific advantages of Allegro’s solutions include:
1.4× chopper stabilization for superior temperature stability and resistance to physical stress
2.Low-voltage (3 V) operation
3.Key performance characteristics specified over the full operating voltage and ambient temperature ranges
4.Industry-leading jitter performance
5.Automotive-grade ruggedness (most products are qualified to AEC Q100)
6.The majority of Allegro’s digital position sensing volume ships into demanding automotive applications, and has a proven quality record and dedication to continuous improvement.
Motor Driver and Interface ICs
Allegro offers an industry leading portfolio of motor driver and controller ICs for brushless DC, brush DC, and stepper motors. Product architectures vary from highly-efficient internal DMOS drivers to MOSFET controller ICs suited for a wide variety of motor applications. Coupled with a strong system level expertise, Allegro’s motor driver IC portfolio provides the user with a high-performance, leading edge and reliable motor control solution.
Allegro's BCD (bipolar, CMOS and DMOS components) technology allows for a wide range of features that is well suited for today’s demanding motor control applications. Allegro motor driver ICs can be found in a number of demanding markets, including automotive, industrial and office equipment. Our products are found in motor driver applications such as automotive pumps and blowers, electronic power steering (EPS) systems, printers (ink-jet and laser) and a variety of cooling fan applications.
