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.
