BQ20Z40PW TI Battery Management IC | 20-TSSOP | SBS 1.1, Impedance Track

Product Overview

The BQ20Z40PW from Texas Instruments is a highly integrated, single-cell Li-Ion and Li-Polymer battery management IC designed for accurate fuel gauging and protection. It features Impedance Track™ technology for precise state-of-charge (SOC) reporting over the battery's lifetime. The device communicates via SMBus v1.1 and is housed in a compact 20-pin TSSOP package, making it ideal for space-constrained portable applications.
