The BQ2057DGK is a linear battery charger integrated circuit designed for single-cell lithium-ion (Li-Ion) and lithium-polymer (Li-Po) battery packs. It provides a programmable constant-current charge profile, allowing the designer to set the charge current to match the battery capacity. The device operates from a 15V supply and regulates the battery pack voltage to 4.1V. The operating temperature range is -20°C to 70°C, making it suitable for a variety of ambient conditions. The charger is housed in a compact 8-VSSOP surface-mount package, which also accommodates 8-TSSOP and 8-MSOP footprints. This IC is intended for applications requiring a dedicated, controlled charging solution for single-cell Li-Ion/Polymer batteries.
