MC34709VK

Document Number: MC34709 Freescale Semiconductor Rev. 4.0, 11/2013 Advance Information Power Management Integrated 34709 Circuit (PMIC) for i.MX50/53 Families The 34709 is the Power Management Integrated Circuit (PMIC) POWER MANAGEMENT designed primarily for use with the Freescale i.MX50 and i.MX53 families. It offers a low cost solution 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. VK SUFFIX (PB-FREE) 98ASA00333D Features 130 MAPBGA Six multi-mode buck regulators for direct supply of the processor 8.0 X 8.0 (0.5 MM PITCH) core, memory, and peripherals. Boost regulator for USB PHY domain on i.MX processors. Applications Eight LDO regulators with internal and external pass devices for Tablets thermal budget optimization and DDR memory voltage reference Smart Mobile Devices 10-bit ADC for monitoring battery and other inputs Real time clock and crystal oscillator circuitry with a coin cell Patient Monitors backup/charger Digital Signage 2 SPI/I C bus for control and register interface Human Machine Interfaces (HMI) Four general purpose low-voltage I/Os with interrupt capability Two PWM outputs 0 1 2 & & % & & % . ) * / , + - ( Figure 1.
