Allegro MicroSystems, Inc. has developed a line of fully integrated Hall-effect current sensor ICs and Hall-effect linear ICs that provide highly accurate, low noise output voltage signals that are proportional to an applied AC or DC current. These current sensor 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.
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 5 A to 200 A. For sensing beyond 200 A, an Allegro current sensor linear 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.
Wherever current sensing is needed, an Allegro sensor IC can provide a solution.
Regulators and Lighting
Allegro MicroSystems, Inc. offers a growing portfolio of DC/DC switching regulators and LED drivers. Allegro¡¯s process technology and applications expertise has enabled the development of highly integrated ICs, providing flexibility and functionality in a small solution footprint. Devices offer buck, boost, charge pump, and linear topologies and aim to provide comprehensive, extremely robust solutions with minimal external components.
The DC/DC regulator portfolio focuses on fully integrated devices with on-chip FETs, and includes single channel and multiple-output devices. Devices are both general purpose and application specific. The lighting portfolio includes LED driver ICs with a wide variety of topologies, channel counts, output currentsMultiple Output Regulators
Multiple output regulators provide two or more outputs from a single input supply. Outputs can be derived from a combination of buck, LDO, boost, or charge pump topologies depending on the application requirements. Automotive and non-automotive devices are available with a variety of package types, most with exposed pad for excellent thermal dissipation.
Automotive voltage and temperature ratings are available on devices in both product portfolios.
