The new A1442 from Allegro MicroSystems Europe is a full-bridge motor-driver integrated circuit which is optimised for driving vibration motors in applications such as mobile telephones, pagers, electronic toothbrushes, hand-held video game controllers and low-power fan motors.

The A3908 from Allegro MicroSystems Europe is a low-voltage bidirectional DC motor driver IC in an ultra-compact package measuring only 2 mm square. Combining a high operating current with a wide operating voltage range, the new device is ideal for use in battery-operated applications including cameras, toys and games, portable printer/scanners and test instrumentation.

The new A8290 and A8291 from Allegro MicroSystems Europe are single low noise block (LNB) convertor regulator ICs for use in analogue and digital satellite receivers.

At Sensor & Test 2008, Allegro MicroSystems Europe is featuring its latest families of Hall-effect sensors, including a number of precision current sensors designed for automotive and industrial applications.

Allegro MicroSystems Europe has introduced a new high-speed, low-noise Hall-effect current sensor which offers 3 kV RMS voltage isolation and a low-resistance current conductor for 50-100 A current measurements. The ACS756 is a next-generation open-loop current sensor with a 125 kHz bandwidth capability, and takes advantage of Allegro's low-loss leadframe technology and the fast response capability of the monolithic Hall-effect sensor IC.

Allegro MicroSystems Europe has introduced a new family of Hall-effect switches and latches which offer superior switching repeatability through their resistance to temperature variations and thermal stresses.

The A3903 from Allegro MicroSystems Europe is a low-voltage bidirectional DC motor driver IC in an ultra-compact package measuring only 2 mm square and 0.55 mm high. The new device has a typical input voltage range of 3 to 5.5 V and produces an output current up to 500 mA. The output uses a full-bridge circuit incorporating source-side linear operation to produce a constant voltage across the motor coil. This regulated output minimises motor volt...

The A4930 from Allegro MicroSystems Europe is a single-phase brushless DC motor pre-driver integrated circuit designed to control high-current devices such as fans, blowers or pumps with supply voltages from 8 V to 36 V.

Two new full-bridge stepper-motor driver ICs, the A4986 and A4987, have been added to the family of motor driver devices available from Allegro MicroSystems Europe. The new devices are dual DMOS full-bridge stepper-motor drivers with parallel input communication and overcurrent protection, and offer improved microstepping accuracy along with high reliability.

The A8295, A8297 and A8298 from Allegro MicroSystems Europe are the latest generation of devices in a family of single and dual low-noise block (LNB) supply and control voltage regulator ICs designed for use in satellite receivers in set-top boxes and LCD television sets.
