Description
General part information
BQ24295 Series
The bq24295 is a highly-integrated switch-mode battery charge management and system power path management devices for 1 cell Li-Ion and Li-polymer battery in a wide range of power bank, tablet and other portable device applications.
Its low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery life during discharging phase. The I2C serial interface with charging and system settings makes the device a truly flexible solution.
The device supports 3.9V – 6.2V USB input sources, including standard USB host port and USB charging port with 6.4V over-voltage protection. The bq24295 is compliant with USB 2.0 and USB 3.0 power specifications with input current and voltage regulation. To set the default input current limit, the bq24295 detects the input source through D+/D– detection following the USB battery charging spec 1.2. In addition, the bq24295 detects non-standard 2A/1A adapters. The bq24295 supports battery boost operation by supplying adjustable voltage 4.55 – 5.5V (default 5.1V) on PMID pin with minimum current of 1.5A.
