The LP4055AQVF with TDFN-6 ROHS is a Battery Management Integrated Circuit (IC) manufactured by LOWPOWER. It is a system-on-chip solution designed for managing battery packs used in handheld and portable devices. The IC provides a single-wire digital serial interface for synchronous communication between the system microcontroller and multiple battery cells. It provides highly accurate voltage and current monitoring, temperature sensing, and charging control. The device also includes features such as timer-controlled safety, sleep mode, fast all-cell cell balancing, and short-circuit protection. Its low operating current and small 6-pin TDFN package make it well-suited to portable device applications. Additionally, the IC is built to meet the latest RoHS requirements.
