MC34709

Roll over image to zoom in

The MC34709 is a power management integrated circuit (PMIC) designed primarily for use with the i.MX 50 and i.MX53 families.

Offers a low cost solution targeting embedded applications that do not require a battery charger
Can be easily combined with an external charger, allowing flexibility for either single or multi-cell Li-Ion battery configurations
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
