General Description

The bq2501x series are highly integrated charge and power management devices targeted at space-limited bluetooth applications.

The bq2501x series offer integrated power FET and current sensor for charge control, reverse blocking protection, high accuracy current and voltage regulation, charge status, charge termination, and a highly efficient and low-power dc-dc converter in a small package.

The bq2501x charges the battery in three phases: conditioning, constant current and constant voltage.

Key Features

  • 1.
  • 2 Li-Ion Or Li-Pol Charge Management and Synchronous DC-DC Power Conversion In a Single Chip.
  • Optimized for Powering Bluetooth™ Headsets and Accessories.
  • Charges and Powers the System from Either the AC Adapter or USB with Autonomous Power Source Selection.
  • Integrated USB Charge Control with Selectable 100 mA and 500 mA Charge Rates.
  • Integrated Power FET and Current Sensor for Up to 500 mA Charge.
