TI Korea (CEO Kent Chon, www.ti.com/ww/kr) June 7, 2013 – TI (CEO Kent Chon) announced the introduction of two new power management chipsets featuring its proprietary MaxLife™ fast charging technology, enabling faster charging of single-cell lithium-ion batteries while extending battery life. These chipsets, which combine bq27530 and bq27531 battery gauge ICs with bq2416x and bq2419x charging ICs, maximize battery performance by minimizing battery degradation while leveraging the fastest possible charging speed.

Generally, batteries exhibit reduced capacity as charge and discharge cycles repeat. TI's MaxLife technology employs an innovative degradation modeling system to extend battery life while minimizing charging time (according to lab test results, up to 30% improvement). Based on the widely-used Impedance Track™ battery capacity measurement technology, the MaxLife algorithm accurately predicts battery capacity and prevents charging conditions that degrade the battery.

Autonomous Battery Management
Traditional software-controlled battery management systems using microcontrollers, PMICs (power management integrated circuits), and DSPs exhibit limited functionality in converting runtime estimates based on accurate battery capacity predictions. The bq27530 and bq24160 chipsets with 2.5A charging speed and bq27531 and bq24192 chipsets with 4.5A charging speed enable the battery gauge IC to directly control the charging IC, providing designers with greater flexibility. This autonomous battery management system reduces software overhead, enhances battery safety and security, and improves thermal management. Additionally, this charging algorithm can support other platforms and new high-capacity batteries.

Development Kit Support
TI provides the latest lithium-ion fast charging development kit featuring the bq27531 battery gauge IC, which communicates directly with the bq24192 using an I2C interface. The evaluation kit's input operating range is 4.2V to 10V.

MaxLife Technology Key Advantages
• Fast charging up to 4.5A maximum with single-cell lithium batteries
• Extended battery life by minimizing runtime degradation from repeated discharge cycles
• Improved thermal management and reduced heat generation for high-efficiency charging
• Accurate capacity prediction and precise control of charging current and termination thresholds through high-performance Impedance Track™ monitoring system
