Torex Semiconductor, Ltd. PMIC - Battery Chargers XC6804B4E1QR-G

The XC6804B4E1QR-G is a linear charger IC designed for single-cell Li-ion and Li-polymer batteries, featuring both Constant-Voltage (CV) and Constant-Current (CC) charging modes. It incorporates a JEITA-compliant temperature detection function, allowing for safe charging by adjusting the charge voltage and current based on battery temperature. The device operates within a voltage range of 4.5V to 6V and supports a charge current that can be set between 200mA and 800mA using external resistors. Key protective features include thermal shutdown, under-voltage lockout, and monitoring for over-voltage and over-current conditions. The XC6804B4E1QR-G is available in compact SOP-8FD and USP-6EL packages, making it suitable for applications in health care devices, power banks, portable audio players, Bluetooth headsets, portable navigation devices, and digital cameras. The operating temperature range is -40°C to +85°C, and the product is compliant with EU RoHS standards.
