詳細說明

The bq2407x series of devices are integrated Li-Ion linear chargers and system power path management devices targeted at space-limited portable applications. The devices operate from either a USB port or an AC adapter and support charge currents up to 1.5 A. The input voltage range with input overvoltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the bq2407x to meet USB-IF inrush current specifications. Additionally, the input dynamic power management (VIN-DPM) prevents the charger from crashing incorrectly configured USB sources. Features• Fully Compliant USB Charger – Selectable 100-mA and 500-mA Maximum Input Current – 100-mA Maximum Current Limit Ensures Compliance to USB-IF Standard – Input-Based Dynamic Power Management (VIN-DPM) for Protection Against Poor USB Sources• 28-V Input Rating with Overvoltage Protection• Integrated Dynamic Power Path Management (DPPM) Function Simultaneously and Independently Powers the System and Charges the Battery• Supports up to 1.5-A Charge Current with Current Monitoring Output (ISET)• Programmable Input Current Limit up to 1.5 A for Wall Adapters• System Output Tracks Battery Voltage (bq24072)• Programmable Termination Current (bq24074)• Battery Disconnect Function with SYSOFF Input (bq24075, bq24079)• Programmable Pre-Charge and Fast-Charge Safety Timers• Reverse Current, Short-Circuit and Thermal Protection• NTC Thermistor Input• Proprietary Start-up Sequence Limits Inrush Current• Status Indication – Charging/Done, Power Good Applications• Smart Phones• Portable Media Players• Portable Navigation Devices• Low-Power Handheld Devices
