The TPS65013 is an integrated power and battery management IC from Texas Instruments for applications powered by one Li-ion or Li-polymer cell and which require multiple power rails. The device provides two highly efficient, step-down converters targeted at supplying the core voltage and peripheral, I/O rails in a processor-based system.
Both step-down converters enter a low-power mode at light load to maximise efficiency. The TPS65013 also integrates two 200 mA LDO voltage regulators, which are enabled via the serial interface. Each LDO operates from 1,8 V and 6,5 V, allowing them to be supplied from one of the converters or directly from the battery.
The TPS65013 also has a highly integrated and flexible Li-ion linear charger and system power management. It offers integrated USB-port and AC-adapter supply management with autonomous power-source selection, power FET and current sensor, high accuracy current and voltage regulation, charge status, and charge termination. The charger automatically selects the USB port or the AC adapter as the power source for the system.
The battery is charged in three phases: conditioning, constant current, and constant voltage. Charge is normally terminated based on minimum current while an internal charge timer provides a safety backup for charge termination.
The serial interface can be used for dynamic voltage scaling, for collecting information on and controlling the battery charger status, for optionally controlling two LED driver outputs, a vibrator driver, masking interrupts, or for disabling/enabling and setting the LDO output voltages. The interface is compatible with the fast/standard mode I²C specification allowing transfers at up to 400 kHz.
