2.3 Battery management
• Battery charge and play system:
– Supports single-cell Li-Ion batteries
– Separate adapter and current-limited USB inputs
– Application can operate from external source when battery is low or not connected
– Battery remains fully charged after charging as long as an external power supply is
connected
– Programmable precharge and fast charge currents
– Integrated power transistors
– Thermal regulation loop controls charge rate at maximum device temperature
• Undervoltage lockout detectors with programmable thresholds
• Backup battery input for RTC supply when main battery is empty
• Backup battery charger.
2.4 ADC
• 10-bit resolution
• 4 input pins
• Analog preprocessor offering input voltage division and subtraction
• Direct and ratiometric measurement modes.
3. Applications
• Hard disk-based portable media players
• Flash-based portable media players
• PDAs
