Rousset, France— Atmel promotes its AT73C211 as the first power management IC for handset add-on modules. "Our AT73C211 is a first in its market," said Michele Casetta, marketing manager for the Power Management and Audio Analog Companion PMAAC Product Line. "The integration of various power supply channels and an ultra-low-power backup supply channel with a power controller circuit for startup and shutdown makes it an ideal companion for every application where power consumption, cost and space are key."
The chip is suited for providing the operating voltage and power management for the digital, analog, interface and RF sections in such modules that add GSM/GPRS, 3G, WLAN, Bluetooth, and GPS functionality to mobile phones and other handheld devices. It integrates a DC/DC converter with power switches to supply digital cores at 1.9 volts and up to 300 mA. Three high-current low drop out (LDO) voltage regulators supply the analog, interface, and RF sections of typical multimedia and wireless communication applications with 2.7 to 2.8 volts at up to 130 mA. An ultra low-power LDO and a back-up battery or supercap charger are also provided to supply the real time clock (RTC) section present in the application processor core. A reset generator and a voltage supervision function are also included.
