| New ISO 26262 / ASIL-D Power Management IC for Automotive Control Units | | Allegro MicroSystems, LLC announces a new power management IC that integrates a buck or buck/boost pre-regulator, four LDOs, and four floating gate drivers. The pre-regulator uses a buck or buck/boost topology to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage complete with control, diagnostics, and protections. Allegro’s ARG82800 device is targeted at the automotive marketwith end applications to include electronic power steering (EPS), transmission control units (TCU), and advanced braking systems (ABS). | | Leer la noticia completa | 18 de Jan de 2018 - 09:39 PM | |
| New Three-phase MOSFET Driver IC with On-board Regulator |  Allegro MicroSystems, LLC announces a new three-phase MOSFET driver IC with an integrated low dropout regulator supplying 5 V or 3.3 V. Allegro’s A4919 is designed for a wide range of industrial applications. It can be controlled with block (trapezoidal), sinusoidal, or vector commutation when interfaced with a microprocessor. The A4919 is designed to be a simple direct control gate driver for both the commercial and industrial markets providing LDO for peripherals or a microprocessor and provide complete flexibility over commutation. | | Leer la noticia completa | 03 de Jan de 2018 - 06:40 PM | |
| Allegro MicroSystems, LLC Introduces Two New Devices to Complement Existing Family of High Bandwidth Current Sensor ICs |  Allegro MicroSystems, LLC adds a new generation of high bandwidth current sensor ICs to their existing family of devices. The Allegro’s ACS732 and ACS733 current sensor ICs provide a compact, fast, and accurate solution for measuring high-frequency currents in DC/DC converters and other switching power applications. These devices are the first 1 Mhz offerings from Allegro to offer 3600 VRMS galvanic isolation ratings. The current sensor ICs are Hall-effect-based and include user-configurable overcurrent fault detection. These features make them ideally suited for high-frequency transformer and current transformer replacement in applications running at high voltages. | | Leer la noticia completa | 21 de Dec de 2017 - 08:30 PM | |
| Allegro MicroSystems, LLC Introduces New 0° To 360° Angle Sensor ICs | | Allegro MicroSystems, LLC introduces a new 0° to 360° angle sensor ICs that provide contactless high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. Allegro’s A1330 devices include a system-on-chip (SoC) architecture that includes: a CVH front end, digital signal processing, and either an analog or digital PWM output signal. | | Leer la noticia completa | 05 de Dec de 2017 - 11:21 PM | |
| New Quad Full-Bridge PWM Motor Driver IC | | Allegro MicroSystems, LLC introduces a new quad DMOS full-bridge driver capable of driving up to two stepper motors or four DC motors. The AMT49701 was designed specifically for dual axis, point of sale, office automation, security, surveillance, IP cameras, as well as industrial automation applications. | | Leer la noticia completa | 27 de Nov de 2017 - 06:43 PM | |
