Texas Instruments TPS65910A Power Management IC
Texas Instruments TPS65910A Power Management IC is dedicated to applications powered by one Li-ion or Li-ion polymer battery cell, 3-series Ni-MH cells, or a 5V input. It requires multiple power rails. This TI device provides three step-down converters, one step-up converter, and eight LDOs and is designed to support the specific power requirements of OMAP-based applications.
Features
- Embedded power controller
- Two efficient step-down DC-DC converters for processor cores
- One efficient step-down DC-DC converter for I/O power
- One efficient step-up 5V DC-DC converter
- SmartReflex™ compliant dynamic voltage management for processor cores
- 8 LDO voltage regulators and one RTC LDO (internal purpose)
- One high-speed I2C interface for general-purpose control commands (CTL-I2C)
- One high-speed I2C interface for SmartReflex Class 3 control and command (SR-I2C)
- Two enable signals multiplexed with SR-I2C, configurable to control any supply state and processor cores supply voltage
- Thermal shutdown protection and hot-die detection
- A real-time clock (RTC) resource with:
- Oscillator for 32.768kHz crystal or 32kHz built-in RC oscillator
- Date, time, and calendar
- Alarm capability
Applications
- Portable and handheld systems
- OMAP3 power management
