XC6806A43511-G

XC6806A43511-G is a XC6806 series lithium-ion linear charger IC with shutdown and current path function. This is equipped with a system power supply function, this 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 450mA 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. Application includes wearable devices, Bluetooth headsets, wireless earphone/Bluetooth earphone, hearing aid, health care devices, IoT sensors.
