ATS系列自适应阀值霍尔齿轮传感器

Using a patented peak-detection technique to eliminate magnet and system offsets, Allegro's ATS611LSB is optimized to sense fine-pitch gears over large working air gaps. The circuit design has the ability to react rapidly to changes, such as those caused by gear wobble and eccentricity, providing stable operation at extremely low rotation speeds. This advanced circuitry is ideal for gathering speed, position, and timing information using fine-pitched gears.

The ATS611LSB provides peak performance for your speed-sensing applications such as transmission and crank position sensing.

3953, 2919, and 5804电机驱动电路

Continuing our leading edge tradition of industry standard motor drivers, the 3953 Full-Bridge Motor Driver is our newest bipolar driver solution. Rated at 50 V and 1.3 A, the A3953 is ideal for driving bipolar stepper motors and DC motors.

The 2919SB and 2919SLB motor drivers are designed to drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. Both bridges are capable of sustaining 45 V and include PWM control of the output currents to 750 mA.

Combining low-power CMOS logic with high-current and high-voltage bipolar outputs, the 5804 BiMOS II Translator/Driver provides complete control and drive for a four-phase unipolar stepper motor.

3966 2916 & 6219 全桥PWM电机驱动电路

3966 2916 & 6219 Dual Full-Bridge PWM Motor Driver delivers high performance and includes many advanced features. Yet it is one of the lowest-priced bipolar stepper motor drivers on the market.

The A3966 is designed to drive both windings of a two-phase bipolar stepper motor. It includes two H-bridges, each capable of continuous output currents of ±650 mA and operating voltages to 30 V.

For over thirty years, Allegro has delivered the products that control the full range of motion better, more reliably, and more accurately than anyone else in the industry. From bidirectional control of servo or stepper motors, to linear and rotary position sensing and more, we put you in command of your motion control applications.

3955 & 3957 is designed for driving one winding of a bipolar stepper motor in a microstepping mode. The outputs are rated for continuous output currents to ± 1.5 A and operating voltages to 50 V. Internal pulse-width modulated (PWM) current control combined with an internal 3-bit/4-bit non-linear digital-to-analog converter allows the motor current to be controlled in full-, half-, quarter-, or eight-step/sixteen-step (microstepping) modes. Nonlinear increments minimize the number of control lines necessary for microstepping. Microstepping provides for increased step resolution, and reduces torque variations and resonance problems at low speed

Low power dissipation and higher power — Allegro's new full-featured A3972 is a serial-controlled microstepping driver with DMOS (all N channel) outputs for decreased power dissipation and higher peak-current capability compared to bipolar drivers.We have it all inside! 6-bit programmable linear DACs offer tailoring to specific motors and reduces the external components.

A6800 系列荧光屏显示驱动电路

If you work with vacuum-fluorescent displays, then you know that electronic noise can really disrupt system capabilities.
