1A, Single-Input, Single Cell Li-Ion and Li-Pol Battery Charger with Auto Start
HL7040C
Message
The HL7040C series of devices are highly integrated Li-Ion and Li-Pol 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 HL7040C 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.
The charger power stage and charge current sense functions are fully integrated. The charger function has high accuracy current and voltage regulation loops, charge status display, and charge termination. The pre-charge current and termination current threshold are programmed via an external resistor on the HL7040C. The fast charge current value is also programmable via an external resistor. HL7040C is available in a 10-pin DFN package.
