The bq2407xT 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 AC adapter and support charge currents up to 1.5A. The input voltage range with input over-voltage protection supports unregulated adapters. The USB input current limit accuracy and start up sequence allow the bq2407xT to meet USB-IF inrush current specification. Additionally, the input dynamic power management (VIN - DPM) prevents the charger from crashing incorrectly configure USB sources.
