产品信息

描述 The bq2409x series of devices are highly integrated Li-ion and Li-Pol linear chargers devices targeted at space-limited portable applications. The devices operate from either a USB port or AC adapter. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters. The bq2409x has a single power output that charges the battery. A system load can be placed in parallel with the battery as long as the average system load does not keep the battery from charging fully during the 10-hour safety timer. The battery is charged in three phases: conditioning, constant current and constant voltage. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded.The charger power stage and charge current sense functions are fully integrated. The charger function has high accuracy current and voltage regulation loops, charge status display, and charge termination. The pre-charge current and termination current threshold are programmed via an external resistor. The fast charge current value is also programmable via an external resistor.特性Charging 1% Charge Voltage Accuracy10% Charge Current AccuracyPin Selectable USB 100-mA and 500-mA Maximum Input Current LimitProgrammable Termination and Precharge ThresholdProtection 6.6 V Over-Voltage ProtectionInput Voltage Dynamic Power Management125°C Thermal Regulation; 150°C Thermal Shutdown ProtectionOUT Short-Circuit Protection and ISET Short Detection Operation Over JEITA Range via Battery NTC – ½ Fast-Charge-Current at Cold, 4.06V at Hot, bq24092/3Fixed 10-Hour Safety TimerSystemAutomatic Termination and Timer Disable Mode (TTDM) for Absent Battery Pack With ThermistorStatus Indication – Charging/DoneAvailable in Small 10-Pin MSOP PackageAPPLICATIONSSmart PhonesPDAsMP3 PlayersLow-Power Handheld DevicesAll other trademarks are the property of their respective owners
