1 Purpose
This document shows an example implementation of an
external battery charger solution for the MC34708 power
management architecture for i.MX processors.
2 Scope
This document provides the design-in information (including
schematic) for using an external battery charger with isolated
charging path while interfacing with the MC34708 PMIC. It
does not provide instruction on how to fully configure the
MC34708 system along with an i.MX processor; however, it
does refer to them in order to provide a clear idea on how the
battery charger would interact in a full system environment.
