i.MX233 Power Management Unit and Battery Charger
The i.MX233 includes a highly-efficient and comprehensive power supply. It is powered by a Li-Ion battery or 5 V power source and generates five internal power rails through two separate supplies. All the hardware in the PMU must be configured through firmware. The i.MX233 requires direct modifications to registers in the power block. Following application note describes the battery charger block and provides instructions to charge a battery. The power savings features of the i.MX233 are also described.http://www.freescale.com/files/dsp/doc/app_note/AN3883.pdf
