The new A3987 from Allegro MicroSystems Europe is a microstepping motor driver IC which combines an output drive capability of 50 V and ±1.5 A with built-in translator circuitry and overcurrent protection. The new device is designed to operate bipolar stepper motors in full, half, quarter and sixteenth step modes, and includes a fixed off-time current regulator which has the ability to operate in slow or mixed decay modes. Typical applications ...

The new A8698 and A8697 from Allegro MicroSystems Europe are the latest additions to the company's range of step-down regulator ICs.

The new A3969 from Allegro MicroSystems Europe is a compact dual full-bridge pulse-width modulated (PWM) motor driver integrated circuit which is ideally suited to applications in portable equipment or where board space is limited.

The A8530 from Allegro MicroSystems Europe is a high-efficiency charge pump integrated circuit that offers a simple, low-cost white LED driver solution for driving four display backlight and two flash/torch video-mode white LEDs.

The new A138X family of Hall-effect sensor integrated circuits from Allegro MicroSystems Europe are programmable, analogue-output devices that are offered in a choice of low-profile surface-mount packages.

The new A3992 from Allegro MicroSystems Europe is a DMOS full-bridge microstepping PWM motor driver integrated circuit designed for the pulse-width-modulated (PWM) current control of bipolar microstepping stepper motors.

The new A1391 and A1392 linear Hall-effect sensor ICs from Allegro MicroSystems Europe are micropower devices that feature a power consumption of only 10 mW in active mode. Despite the low power consumption, the features required to produce a highly accurate linear Hall effect IC have not been compromised.

The A3986 from Allegro MicroSystems Europe is a dual full-bridge gate driver IC with integrated microstepping translator circuitry. The device is suitable for driving a wide range of industrial bipolar 2-phase stepper motors in the 30 to 500 W power range. Motor power is provided by external N-channel power MOSFETs at supply voltages from 12 to 50 V.
