The BQ24060DRCT is a highly integrated Li-ion and Li-polymer Linear Charger targeted at space-limited portable applications. The BQ2406x series offers a variety of safety features and functional options, while still implementing a complete charging system in a small package. The battery is charged in three phases: conditioning, constant or thermally regulated current and constant voltage. Charge is terminated based on minimum current. An internal programmable charge timer provides a backup safety feature for charge termination and is dynamically adjusted during the thermal regulation phase. The BQ2406x automatically re-starts the charge if the battery voltage falls below an internal threshold; sleep mode is set when the external input supply is removed. Multiple versions of this device family enable easy design of the BQ2406x in cradle chargers or in the end equipment, while using low cost or high-end AC adapters.
● Ideal for low-dropout designs
● Integrated power FET and current sensor for up to 1A charge applications
● Reverse leakage protection prevents battery drainage
● Thermal regulation maximizes charge rate
● Charge termination by minimum current and time precharge conditioning with safety time
● Short-circuit and thermal protection
● Automatic sleep mode for low power consumption
● Selectable battery insertion and battery absent detection
● Input overvoltage protection
● Green product and no Sb/Br
●Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
