Description

The TPS65014RGZRG4 is an integrated power and battery management IC for applications powered by one Li-ion or Li-polymer cell and which require multiple power rails. The TPS65014RGZRG4 provides two highly efficient, step-down converters targeted at providing 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 for maximum efficiency across the widest possible range of load currents. The LOW_PWR pin allows the core con- verter to lower its output voltage when the application processor goes into deep sleep. The TPS65014RGZRG4 also integrates two 200-mA LDO voltage regulators, which are enabled via the serial interface. Each LDO TPS65014RGZRG4 operates with an input voltage range between 1.8 V and 6.5 V, allowing them to be supplied from one of the step-down converters or directly from the battery.

The TPS65014RGZRG4 also has a highly integrated and flexible Li-Ion linear charger and system power man- agement. 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 TPS65014RGZRG4 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 100mA to 500 mA via the interface. In theac-adapter configuration, an external resistor sets the maximum value of charge current.

The battery of TPS65014RGZRG4 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 TPS65014RGZRG4 automatically restarts the charge if the battery voltage falls below an internal threshold. The charger automatically en- ters sleep mode when both supplies are removed.
