17 / 63 page  TPS65010 www.ti.com SLVS149C – JUNE 2003 – REVISED SEPTEMBER 2015 7 Detailed Description 7.1 Overview The TPS65010 charger automatically selects the USB-Port or the ac-adapter as the power source for the system. In the USB configuration, the host can increase the charge current from the default value of maximum 100 mA to 500 mA through the interface. In the ac-adapter configuration an external resistor sets the maximum value of charge current. The battery is charged in three phases: conditioning, constant current, and constant voltage. Charge is normally terminated based on minimum current. An internal charge timer provides a safety backup for charge termination. The TPS65010 automatically restarts the charge if the battery voltage falls below an internal threshold. The charger automatically enters sleep mode when both supplies are removed. The serial interface can be used for dynamic voltage scaling, for collecting information on and controlling the battery charger status, for optionally controlling 2 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 specification allowing transfers at up to 400 kHz. Battery Charger, Step-Down Converters, LDOs, UVLO protection, Rail Sequencing, Vibrator Driver, and various logic level controls. The LOW_PWR pin allows the core converter to lower its output voltage when the application processor goes into deep sleep.
