Description

The BQ24025DRCR is high integrated and flexible Li-Ion linear charge and system power management device targeted at space limited charger application.The BQ24025DRCR offer integrated USB-port and ac-adapter supply management with autonomous power-source selection, power FET and current sensor, high-accuracy current and voltage regulation,charge status, and charge termination, in a single monolithic device.

The BQ24025DRCR automatically selects the USB-Port or the ac-adapter as the power source for the system. In the USB configuration, the host can select from the two preset charge rates of 100 mA and 500 mA. In the ac−adapter configuration an external resistor sets the magnitude of the system or charge current.

The BQ24025DRCR charges 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 for charge termination. The BQ24025DRCR automatically restarts the charge if the battery voltage falls below an internal threshold. The BQ24026DRCR automatically enters sleep mode when both supplies are removed.
