800mA, Single-Input, Single Cell Li-Ion Battery Charger With Auto Start

The bq24040 BQ24041 series of devices are highly integrated Li-ion linear chargers devices targeted at space-limited portable applications. The devices operate from either a USB port or AC adapter. The high input voltage range with input overvoltage protection supports low-cost unregulated adapters. The bq24040 BQ24041 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. In all charge phases, an internal control loop monitors the IC junction temperature and reduces the charge current if an internal temperature threshold is exceeded. By Texas Instruments
