Power Management Controller Targets Intel Cellular Platforms

Dialog Semiconductor Plc recently announced the introduction of a new power management controller aimed at high-functionality single- and dual-mode wideband CDMA as well as GSM/GPRS smart phones. The controller, Arava, was developed with Intel Corp. as part of the ongoing development and marketing initiative between Dialog Semiconductor and Intel to support existing and future Intel Personal Internet Client Architecture (Intel PCA) system level products.

The Arava device will support the new cellular processor family from Intel, named Hermon, disclosed by Intel at the 3GSM Congress in Cannes as well as the upcoming Bulverde processor.

As with other products in this series of power-management controller ICs, Arava will provide the necessary power-management functions for advanced handset designs, including support for an applications processor (Bulverde) as well as the main communications processor (Hermon).

The device, which connects directly to the battery, provides stable, low noise supplies for all core circuits within the phone, with additional regulators for enhanced application capabilities, such as Bluetooth modules, camera modules, and SD memory cards. All supplies are fed using high-performance low-dropout (LDO) voltage regulators using Dialog Semiconductor’s patented Smart Mirror technology, which offers very low quiescent current consumption and high power-supply rejection performance.
