Dual Input Charger With Integrated Synchronous Buck Converter, Output Adjustable

The BQ25015 7 are highly integrated charge and Power Management devices targeted at space-limited Bluetooth applications. The BQ25015 7 devices 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 BQ25015 7 devices charge the battery in three phases: conditioning, constant current and constant voltage. Charge is terminated based on minimum current. An internal charge Timer provides a backup safety feature for charge termination. The BQ25015 7 automatically re-starts the charge if the battery voltage falls below an internal threshold. The BQ25015 7 automatically enters sleep mode when VCC supply is removed.
The integrated low-power high-efficiency DC-DC Converter is designed to operate directly from a single-cell Li-ion or Li-Pol battery pack. The output voltage is either adjustable from 0.7 V to VBAT, or fixed at 1.8 V BQ25017 and is capable of delivering up to 300-mA of load current. The DC-DC Converter operates at a synchronized 1 MHz switching frequency allowing for the use of small inductors.
