| Summit Hot-Swap Controller Minimizes Power Dissipation, System Cost
and Board Space | | San Jose, Calif. - Summit Microelectronics has expanded its programmable
power management family with the introduction of an innovative, dual-feed active OR'ing hot-swap controller. The
SMH4814 device can monitor and control two independent -48V feeds, allowing for redundant power supply control.
Furthermore, it eliminates the need for passive OR'ing diodes, which are bulky and significantly contribute to
system power dissipation. Using Summit's GUI-based, non-volatile programming technology, system designers can
customize the SMH4814 to address their specific power management and control requirements while using a single part
number for different platforms. | | Leer la noticia completa | Jueves, 06 Octubre, 2005 - 08:35 | |
| | | Cirrus Logic Power Meter IC Provides Precision Measurement for High
Performance | | AUSTIN, Texas – With the introduction of the CS5461A and CS5463 high precision
power meter integrated circuits (ICs) from Cirrus Logic Inc. , digital power meter manufacturers are afforded a
simple upgrade path for next-generation power measurement applications. Pin-to-pin compatible with Cirrus Logic’s
popular CS5460A, these ICs provide additional features such as apparent and reactive power, allowing for shortened
development time, simplified bill-of-materials for next-generation meters. | | Leer la noticia completa | Miércoles, 05 Octubre, 2005 - 11:00 | |

| Emitter-Switched Bipolar Transistors from STMicroelectronics Set New
Standard fo | | Geneva - STMicroelectronics has introduced a family of hybrid
Emitter-Switched Bipolar Transistors (EBST®) particularly suitable for industrial three-phase auxiliary power
supplies and Single-Ended Primary Inductance Converters (SEPIC) used as power factor pre-regulators in industrial
lighting applications. By offering the industry’s best combination of low forward voltage drop, high blocking
voltage and fast switching speed, the new ESBT series represents a breakthrough in the area of high voltage, high
switching frequency applications. | | Leer la noticia completa | Miércoles, 05 Octubre, 2005 - 11:00 | |
| | | STMicroelectronics Launches World’s First Industrial Microcontrollers
based on A | | Geneva – STMicroelectronics has introduced the world’s first family of
ARM-based microcontrollers, the STR730F series, that is specifically designed to address the emerging demand for
high-performance, cost-effective and off-the-shelf 32-bit microcontrollers optimised for industrial applications
such as factory automation, appliances, test and measurement equipment, point-of-sale terminals, and security
systems. A single 5V power rail is the preferred supply configuration for industrial applications that need robust
operation, especially in terms of noise immunity, and the STR730F family is the first family of ARM-based
microcontrollers to meet this need. In addition, the devices are specified over an extended temperature range of
-40°C to +105°C and include a particularly rich set of peripherals tailored for industrial applications, thereby
providing further cost reductions in these competitive applications. | | Leer la noticia completa | Miércoles, 05 Octubre, 2005 - 11:00 | |

| | | STMicroelectronics’ Buck/Boost Converter for High-Power Camera-Flash
LEDs Cuts S | | Geneva – STMicroelectronics has introduced a new power-supply IC, the STCF02,
that is specifically designed to drive the high-current white LEDs used for flash illumination in the latest
generation of mobile imaging equipment such as cameras for mobile phones, digital still cameras, and PDAs. In
addition to supporting the higher flash illumination powers required by the latest high-resolution image sensors,
the device extends battery life thanks to the extremely low standby current of less than 1 microamp that it draws
during shutdown mode, one-sixth of the power consumed by alternative devices. The STCF02 also incorporates
comprehensive protection circuitry, including, uniquely, the ability to automatically sense and respond to excessive
LED temperature. | | Leer la noticia completa | Miércoles, 05 Octubre, 2005 - 11:00 | |
