TPS65014SLVS551A –DECEMBER 2004–REVISED SEPTEMBER 2015
TPS65014 Power- and Battery-Management IC for Li-Ion Powered Systems Features 3 DescriptionThe TPS65014 deviceis an integrated power- and Linear Charger Managementfor Single Li-Ionor battery-management IC for applications powered byLi-Polymer Cells one Li-ion or Li-polymer cell and which require• Dual Input Portsfor Charging From USBor From multiple power rails. The TPS65014 provides twoWall Plug, Handles 100-mA and 500-mA USB highly efficient, step-down converters targeted atRequirements providing the core voltage and peripheral I/O railsina
processor-based system. Both step-down converters• Charge Current Programmable Through External
entera low-power modeat light load for maximumResistor efficiency across the widest possible rangeof load• 1-A, 95% Efficient Step-Down Converterfor I/O currents. The LOW_PWR pin allows the coreand Peripheral Components (VMAIN) converter to lower its output voltage when the 400-mA, 90% Efficient Step-Down Converter for application processor goes into deep sleep. The
Processor Core (VCORE) TPS65014 also integrates two 200-mA LDO voltage
regulators, which are enabled through the serial• 2× 200-mA LDOs for I/O and Peripheral interface. Each LDO operates with an input voltageComponents, LDO Enable Through Bus rangeof 1.8Vto 6.5V, thus allowing themto be• Serial Interface Compatible WithI2C, Supports supplied from one of the step-down converters or100-kHz, 400-kHz Operation directly from the battery.
