The 34709 is the Power Management Integrated Circuit (PMIC) designed primarily for use with the Freescale i.MX50 and i.MX53 families. It offers a lower cost alternative to the MC34708, targeting embedded applications that do not require a battery charger. However, it can be easily combined with an external charger, allowing flexibility for either single or multi-cell Li-Ion battery configurations. It supports both consumer and industrial applications with a single 130-pin 8x8 MAPBGA 0.5 mm pitch package that is easily routable in low cost board designs.

Features

? Five buck converters configurable to provide up to six independent outputs for direct supply of the processor core, memory, and peripherals.

? Boost regulator for USB PHY domain on i.MX processors.

? Seven LDO regulators with internal and external pass devices for thermal budget optimization

? One low current, high accuracy, voltage reference for DDR memory

? 10-bit ADC for monitoring battery and other inputs

? Real time clock and crystal oscillator circuitry with a coin cell backup/charger

? SPI/I2C bus for control and register interface

? Four general purpose low-voltage I/Os with interrupt capability

? Two PWM outputs
