Power Management Integrated

Circuit (PMIC) for i.MX50/53

Families

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
