LED backlight driver IC for large displays
The new A8512 from Allegro MicroSystems Europe is a multi-output white LED RGB driver IC for the LED backlighting of large-area LCD monitors and television screens. The new device integrates a scalable-output boost controller operating in constant-frequency current mode control - adjustable between 300 kHz and 1 MHz - driving an external MOSFET. It integrates six internal current sinks each capable of sinking up to 80 mA, which can be combined to...
User-programmable linear Hall-effect sensor IC
The new A1356 from Allegro MicroSystems Europe is a user-programmable linear Hall-effect sensor IC with a pulse width modulated (PWM) output. Featuring built-in filtering to provide low jitter and high sensing accuracy, the new product complements Allegro's existing line of linear devices with PWM outputs by offering a device with a significantly higher carrier frequency of 2 kHz, allowing it to resolve rapid changes in magnetic field.
Constant-current LED driver features 16 channels and 7-bit dot correction
New from Allegro MicroSystems Europe is the A6285, a 16-channel constant-current LED driver featuring individual channel current adjustment via a 7-bit dot correction register. Each channel of the A6285 can sink a constant current up to 80 mA, and a single external resistor sets the maximum LED drive current for all channels. Each channel's drive current can be individually adjusted from 0 to 100% of the maximum value via the dot correction regi...
Motor-driver IC features integrated Hall-element commutation circuitry for driving vibration motors
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.
Low-voltage DC motor driver IC from Allegro
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.
LNB voltage regulator ICs for satellite receiver applications
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.
Allegro features latest Hall-effect sensor developments
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.
Next-generation Hall-effect current sensor from Allegro combines high speed and low noise for 50-100 A current measurements
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.
Hall-effect switches and latches from Allegro
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.
DC motor driver IC from Allegro has typical input voltage range of 3 to 5.5V
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...
