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.

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.

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.
