Lexington, Mass.—STMicroelectronics' STw4810 is a highly integrated power management IC for multimedia application processor engines (APEs) such as ST’s STn881x Nomadik processors. The STw4810 includes multiple DC/DC converters and programmable regulators, processor supply monitoring and reset capabilities, and USB-OTG (USB On-The-Go) support for mobile phone and other portable applications.
The STw4810 includes two independent DC/DC step-down converters, providing 1 to 1.5 volts at up to 600 mA for the core supply, and 1.8 volts at 600 mA for I/O functions and general-purpose use. Three low-dropout programmable regulators supply power for auxiliary devices and peripherals.
The chip also integrates a USB-OTG module, which includes a full speed (12 Mbps) and low-speed (1.5 Mbps) transceiver, USB-cable power supply with 100 mA capability, and a linear regulator. This interface is CEA-936-A Carkit compliant.
Support for market-standard external memory cards, including SD, MMC (52 MHz high speed) and SDIO, is provided by level shifters and a linear regulator. SDIO (secure digital input-output) support enables the connection of multimedia peripherals such as cameras. The STw4810 also includes processor supply monitoring and reset functions, and two I2C control interfaces.
