Analog, Mixed Signal and Power Management MC34708 Power Management Integrated Circuit Designed for the Freescale i.MX50/53 Families Applications • • • • • • • • Tablets Smart mobile devices eReaders Digital signage Telehealth Video-enabled IP phones Portable navigation devices HMI for appliances, building control, factory/home automation, printers and security panels Overview The MC34708 Power Management Integrated Circuit (PMIC) represents a complete system power solution in a single package, designed specifically for use with the Freescale i.MX50/53 families. It integrates six multi-mode buck regulators and eight LDO regulators for direct supply of the processor core, memory and peripherals. This device is powered by SMARTMOS technology. The USB switch enables the use of a single, mini or micro USB connector for USB, UART and audio connections. It automatically identifies the type of device connected. In addition, the MC34708 also integrates a real time clock, coin cell charger, a 16-channel 10-bit ADC, 5.0 V USB boost regulator, two PWM outputs, touch-screen interface, general purpose LED drivers and four GPIOs. The MC34708 is available in pin compatible 8x8 and 13x13 packages.
