- **Output Voltage Rails:**  
  - 3x Step-Down DC-DC Converters (Buck Regulators)  
  - 6x Low-Dropout (LDO) Regulators  
- **Battery Charger:**  
  - Supports single-cell Li-Ion/Li-Polymer batteries  
  - Programmable charge current up to 1.5A  
  - Thermal regulation for safe charging  
- **Power Sequencing:**  
  - Configurable startup and shutdown sequencing  
- **Dynamic Voltage Scaling (DVS):**  
  - Supports processor voltage scaling for power optimization  
- **Protection Features:**  
  - Overvoltage, undervoltage, and overcurrent protection  
  - Thermal shutdown  
- **Interface:**  
  - I²C-compatible control interface for configuration  
- **Package:**

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

SINGLE-CELL Li-ION BATTERY- AND POWER-MANAGEMENT IC

Alternative Part Number

  • MAX17083ETG+ --: Integrated PMIC for portable devices with similar multi-rail power management functions; different vendor and naming, suitable as a functional substitute after pinout verification.
  • BD71837MWV --: Highly integrated power management IC for battery-powered systems offering comparable regulator rails; different series and manufacturer, good second-choice alternative.
  • DA9063 --: Configurable system PMIC with multiple buck and LDO outputs covering similar power management needs; distinct naming and vendor, viable third option with design review.
  • MAX17065ETL+ --: Integrated power-management IC for handheld devices with similar multi-rail regulation and battery-charging functions; different series and vendor, suitable as a functional cross-reference.
  • FAN53555UCX --: High-efficiency programmable buck regulator often used in portable power designs; different series and vendor, usable as a partial functional alternative where full PMIC integration is not required.
