The devices – 6.6V Over-Voltage Protection operate from either a USB port or AC adapter. The high input voltage range with input overvoltage – Input Voltage Dynamic Power Management protection supports low-cost unregulated adapters. – 125°C Thermal Regulation; 150°C Thermal Shutdown Protection The bq2409x has a single power output that charges the battery. A system load can be placed in parallel – OUT Short-Circuit Protection and ISET with the battery as long as the average system load Short Detection does not keep the battery from charging fully during – Operation Over JEITA Range via Battery the 10 hour safety timer. NTC – ½ Fast-Charge-Current at Cold, The battery is charged in three phases: conditioning, 4.06V at Hot, bq24092/3 constant current and constant voltage. In all charge – Fixed 10 Hour Safety Timer phases, an internal control loop monitors the IC • SYSTEM junction temperature and reduces the charge current if an internal temperature threshold is exceeded. – Automatic Termination and Timer Disable Mode (TTDM) for Absent Battery Pack With Thermistor – Status Indication – Charging/Done – Available in Small 10-Pin MSOP Package 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.
