A new family of constant-current LED driver ICs designed to address the emerging requirements of internal and external illumination applications in the automotive market is now available from Allegro MicroSystems Europe.

Allegro MicroSystems Europe has introduced the first family of programmable Hall-effect linear sensors available in miniature package options: TO-92 (3-lead, single in-line package) or SOT-23W (3-lead, surface mount).

The new A6850 from Allegro MicroSystems Europe is a dual-channel switch interface IC designed to simplify the implementation of two-wire Hall-effect sensor systems in automotive applications. The new device eliminates the need for an external sense resistor and comparator, thereby reducing system costs. The elimination of the sense resistor also results in a subsequent elimination of the voltage drop across the resistor, which can enable sensing ...

Four new DMOS microstepping motor driver ICs featuring built-in overcurrent protection and targeted at the office automation market are now available from Allegro MicroSystems Europe. The new A4982/A4984/A4985 and A4988 are complete microstepping motor drivers, each using a simple ‘step’ and ‘direction’ interface and featuring a built-in translator for easy operation. The highly integrated devices require few external components, and occu...

The new A4941 from Allegro MicroSystems Europe is a three-phase, sensorless, brushless DC motor driver IC designed for fan and blower applications in the white goods and office automation sectors. Key features of the new device, which is housed in a small eTSSOP package, include sensorless commutation, a wide (5-16 V) supply voltage range, 1.25 A peak output current, -40° to +105°C operating temperature range, lock detection with auto restart...

The new A5303 from Allegro MicroSystems Europe is a low-current BiCMOS photoelectric smoke detector integrated circuit designed to be used with an infrared optical chamber to sense light scattered from smoke particles.

The ACS760 from Allegro MicroSystems Europe is a hot-swap protection IC designed for 12 V high-side applications. The new device combines Allegro's Hall-effect current sensing technology with hot-swap control circuitry, resulting in a highly efficient integrated controller. No external sense resistor is required, resulting in greatly reduced I2R losses in the power path.

The new A3290 and A3291 from Allegro MicroSystems Europe are temperature-stable and stress-resistant Hall-effect latches in small, robust packages. Superior high-temperature performance is made possible through dynamic offset cancellation, which reduces the residual offset voltage normally caused by device package over moulding, temperature dependencies, and thermal stress. The two devices are targeted at non-automotive applications and are ident...

Engineers at the Allegro MicroSystems Europe Sensor Applications Centre in Annecy, France, have developed a software simulator for the company's automotive Hall-effect sensors that has dramatically reduced development times and eased interaction with customers.

Allegro MicroSystems Europe has introduced the A1360/1/2 family of programmable linear Hall-effect sensor ICs feature extremely low noise levels and very high bandwidth, making them ideally suited to high-frequency automotive or industrial current sensing applications.
