bq21040 Li-Ion & Li-Pol Battery Charger Texas Instruments bq21040 Li-Ion and Li-Pol Battery Charger is a highly integrated linear battery charger targeted at space-limited portable applications. The charger device operates from either a USB port or AC adapter. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters. The Texas Instruments bq21040 has a single power output that charges the battery. A system load can be placed in parallel with the battery as long as the average system load does not keep the battery from charging fully during the 10-hour safety timer. The battery is charged in three phases: conditioning, constant current, and constant voltage. An internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded in all charge phases.
