Blue light-emitting diodes available from Allegro
A range of blue light-emitting diodes developed by Sanken Electric is now available from Allegro MicroSystems Europe.
It is available in 50 and 100A versions, and operates over the industrial temperature range from -20 to +85C.
The device runs off a single +5V supply, provides 3kV isolation, and has a resistance of only 130uohm.
A precisely controlled self-aligning assembly process (patents pending) and factory programming of the linear Hall sensor combine to provide a high level of performance, uniformity and low thermal drift.
The innovative, lead-free electromechanical package integrates the current path, so that there is no need for the user to design a magnetic circuit or thread a conductor through the device.
The package consists of two primary leads that pass the current through a concentrator core and past the sensing element of a Hall-effect integrated circuit.
It requires minimal effort to implement on a PC board in a high-volume production environment and may be soldered or welded.
The volume of the package is less than one-eighth that of competing current sensors.
The ACS752 is ideally suited to applications where isolation, low power dissipation, and low voltage drop are an advantage.
Typical uses are in motor control, power-supply load management, power distribution or overcurrent fault protection.
