Rev. 1.0, 8/2012
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/I
2
C bus for control and register interface
• Four general purpose low-voltage I/Os with interrupt capability
• Two PWM outputs
