Product Description

Description:

  • 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.
