Description
General part information
BQ25176J Series
The BQ25176J is an integrated 800-mA linear charger for 1-cell Li-Ion, Li-Polymer, and LiFePO 4 batteries targeted at space-limited portable applications. The device has a single power output that charges the battery. The system load can be placed in parallel with the battery, as long as the average system load does not prevent the battery from charging fully within the safety timer duration. When the system load is placed in parallel with the battery, the charge current is shared between the system and the battery.
The device has four phases for charging a Li-Ion/Li-Poly battery: trickle charge to bring the battery voltage up to V BAT_SHORT, precharge to recover a fully discharged battery, fast-charge constant current to supply the bulk of the charge, and voltage regulation to reach full capacity.
In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold, T REG, is exceeded.
