STBC02AJR ST Battery Management IC | 30-UFBGA, FCBGA | Li-Ion, 4.2V

Product Overview

The STBC02AJR is a highly integrated battery management IC from STMicroelectronics, designed for single-cell Li-Ion and Li-Polymer battery-powered applications. It combines a linear charger with a 150 mA low-dropout regulator (LDO), a 200 mA true load switch, a 1.8 V/3.3 V regulated output, and a battery voltage monitor. Housed in a compact 30-UFBGA or FCBGA package, it offers a complete power management solution for space-constrained devices.
