High-efficiency fault-tolerant LED driver with wide input voltage range- Fully integrated solution provides 240 mA total current across two channels

The new A1174 from Allegro MicroSystems Europe is an ultrasensitive micropower Hall-effect latch IC with internally or externally controlled sample and sleep periods for use in portable devices that employ rotational speed and direction sensing systems such as tracker balls or scroll bars for PDAs, mobile phones or MP3 players.

The A1172 from Allegro MicroSystems Europe is an ultra-sensitive micropower Hall-effect switch with complementary, latched digital outputs and omnipolar magnetic actuation. The new device features operation at low supply currents and voltages, making it ideal for battery-operated electronics. The combination of a low operating supply voltage (1.65 V to 3.5 V) and a unique clocking algorithm assists in reducing the average operating power consumpt...

New from Allegro MicroSystems Europe, the A1444 and A1445 are low-voltage full-bridge brushless DC motor driver ICs with integrated Hall commutation and internal PWM (pulse-width-modulation) speed control. Designed for applications that require rotor speed control and fast rotor start/stop cycles, the new devices are based on a high-density CMOS semiconductor process that allows the integration of a Hall element, an H-bridge output driver and PWM...

The new A4979 from Allegro MicroSystems Europe is a programmable stepper motor driver IC with microstepping capability and improved programmability and diagnostics. The new device is a flexible microstepping motor driver with a built-in translator for easy operation. It offers a single-chip solution for operating bipolar stepper motors in full-, half-, quarter- and sixteenth-step modes at voltages up to 50 V and currents up to 1.5 A.

The ACS711 from Allegro MicroSystems Europe is a Hall-effect linear current sensor IC with a built-in overcurrent fault output that provides economical and precise AC or DC current sensing in audio, communications, white goods, and automotive applications operating at voltages up to 100 V.

New from Allegro MicroSystems Europe, the A1244 is a two-wire Hall-effect latch featuring on-chip transient protection and a zener clamp to protect against overvoltage conditions on the supply line. The new device, which is programmed at the factory to optimise the magnetic switch point accuracy, uses the same patented high-frequency, 4-phase, chopper-stabilisation technique that is used on the company's complementary family of unipolar switches....
