|A1688 Sensor IC - The A1688 is a Hall-Effect-based integrated circuit (IC) that provides a user-friendly solution for true zero-speed digital ring magnet and gear tooth sensing in two-wire applications. The A1688 is offered in the UB package, which integrates the IC and a high-temperature ceramic capacitor in a single overmolded SIP package. The integrated capacitor provides enhanced EMC performance with reduced external components. The A1688 is a replacement for the A1642 two-wire true zero-speed miniature differential peak-detecting sensor IC with continuous calibration. It is targeted for the automotive market in ABS wheel-speed sensor applications.
|Motor Drive ICs - Allegro offers an industry-leading portfolio of motor driver and controller ICs for brushless DC, brush DC, and stepper motors. Product architectures vary from highly-efficient internal DMOS drivers to MOSFET controller ICs suited for a wide variety of motor applications. Coupled with a strong system-level expertise, Allegro’s motor driver IC portfolio provides the user with a high-performance, leading-edge and reliable motor control solution.
|Allegro A8651 Buck Regulator - The A8651 is a dual 2 A, low Vin, synchronous regulator. The A8651 has adjustable frequency, integrates a high-side, P-channel MOSFET and a low-side, N-channel MOSFET. The A8651 incorporates current-mode control to provide simple compensation, excellent loop stability. The A8651 utilizes external compensation to accommodate a wide range of power components to optimize for transient response without sacrificing stability.
|ATS601 Single Element, Tooth Detecting Speed Sensor IC - The ATS601LSG is a unique addition to Allegro’s camshaft sensor family of products. As a single-element, non-TPOS sensor it provides first falling edge detection, high-accuracy running-mode edge accuracy, and direction/orientation insensitivity over the full operating range of air gap, speed, and temperature. The ATS601LSG is a true zero-speed gear-tooth sensor IC consisting of an optimized Hall IC and simple magnetic pellet configuration ideal for phased cam, start/stop engine applications.
