XC6806 Datasheet | Torex Semiconductor

DESCRIPTION Equipped with a system power supply function, the XC6806 is a linear charger IC for single-cell lithium ion batteries and lithium polymer batteries. The current path function gives system power supply priority over charging the lithium ion battery. The charge current can be adjusted with an external resistance, and an internal limit circuit with an input current of 450m A automatically reduces the charging current based on the load current that flows to the system. The lithium ion battery temperature is monitored in conformance with JEITA, and by controlling the charge voltage and charge current as appropriate for the temperature, the battery can be charged safely. Internal protective functions include the charge timer, UVLO, thermal control, and reverse current prevention. Shutdown function pletely shuts off power supply from the battery to the system to prevent battery leakage current while the device is not in use, and this enables longer use of low supply current devices that operate using a small battery. Charge status, connection status with USB can be confirmed with CSO terminal and PGB terminal. The IC is mounted in the small, high heat dissipation USP-10B or LGA-10B01 package, and a charging circuit can be designed with minimal external ponents. - APPLICATIONS - Wearable devices - Bluetooth headsets - Wireless earphone/Bluetooth earphone - Hearing Aid - Health care devices - Io T sensors - FEATURES Operating Voltage Range Charge Voltage Charge Current Input Current Limit Battery Sink Current Functions : 4.5 ~ 5.5V : 3.50V ~ 4.45V ±30m V : 10m A ~ 385m A Can be set by external resistance : 450m A, fixed internally 0.1μA (Attached Battery only) : Current Path : JEITA Conforming Thermistor Detect : Shutdown Protection Function Operating Ambient Temperature Package Environmentally Friendly : Charge Timer : UVLO : Thermal Control : Reverse Current Prevention : -40°C ~ 85°C : USP-10B, LGA-10B01 : EU Ro HS pliant, Pb Free - TYPICAL APPLICATON CIRCUIT Li-ion...
