1 / 70 page  LP3913 www.ti.com SNVS489I – NOVEMBER 2006 – REVISED SEPTEMBER 2013 LP3913 Power Management IC for Flash Memory-Based Portable Media Players Check for Samples: LP3913 1 FEATURES APPLICATIONS 2 • 2 Low-Dropout Regulators -- LDO1 is Used for • Flash-Based Portable Media Players General Purpose Applications, LDO2 is Used • Portable Gaming Devices for Low-Noise Analog Applications. Both • Portable Navigation Systems LDOs Have Programmable Output Voltages. • Green and Red LED Charger Status Drivers DESCRIPTION • 4-Channel 8-Bit Dual Slope A/D Converter The LP3913 is a programmable system power management unit that is optimized for Flash Memory • 3 High-Efficiency DVS Buck Converters based Portable Media Players. • 400 kHz I2C Compatible Interface The LP3913 incorporates 2 low-dropout LDO voltage • Linear Constant-Current/Constant-Voltage regulators, 3 integrated Buck DC/DC converters with Charger for Single Cell Lithium-Ion Batteries Dynamic Voltage Scaling (DVS), a 4-channel 8-bit • USB and Adapter Charging A/D converter, and a dual source Li-Ion/polymer • System Power Supply Management battery charger. The charger has the capability to charge and maintain a single cell battery from a • 6x6 x 0.8 mm 48 WQFN Package regulated wall adapter or USB power. When both • Voltage and Thermal Supervisory Circuits USB and adapter sources are present, then the • Continuous Battery Voltage Monitoring adapter source takes precedence and switching between USB and adapter power sources is • Interrupt Request Output with 8 Sources seamless. In addition, the battery charger supports • LP3913 is Pin-for-Pin and Software-Compatible power routing, which allows system usage with the LP3910 Hard Drive Based PMIC immediately after an external power source has been detected. The LP3913 also incorporates some KEY SPECIFICATIONS advanced battery management functions such as battery temperature measurement, reverse current • LDO1: 150 mA, 1.2V–3.3V blocking for USB, LED charger status indication, • LDO2: 150 mA, 1.3V–3.3V thermally regulated internal power FETs, battery • Buck1: 600 mA, 0.8V–2.0V voltage monitoring, over-current protection and a 10–hour safety timer. • Buck2: 600 mA, 1.8V–3.3V • Buck3: 500 mA, 1.8V–3.3V The 4-channel A/D converter measures the battery voltage and charge current, which can be used for • 50 m Ω Battery Path Resistance fuel gauging. Two undedicated channels can be used • 100 mA to 1000 mA Full-Rate Charge Current to measure other analog parameters such as Using Wall Adapter discharge current, battery temperature, keyboard • Selectable 0.05C and 0.1C EOC Current resistor scanning and more. • USB Current Limit of 100 mA, 500 mA, and 800 The various IC parameters are programmable mA through a 400 kHz I2C compatible interface. • USB Pre-Qual Current of 50 mA The LP3913 is available in a thermally-enhanced • Selectable 4.1V, 4.2V or 4.38V battery 6x6x0.8 mm 48 WQFN package and operates over termination voltages an ambient temperature range of –40°C to +85°C. • 0.35% Battery Termination Accuracy • ±1 LSB INL/DNL on 8-bit A/D Converter 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
