BQ78350DBTR-R1A TI Battery Monitor | 30-TSSOP | SBS 1.1, CEDV

Product Overview

The BQ78350DBTR-R1A is a Li-Ion battery management controller from Texas Instruments, designed for use with the BQ769x0 family of analog front-end (AFE) devices. It provides accurate monitoring, balancing, and protection for multi-cell battery packs. The device integrates a fuel gauge based on the CEDV (Compensated End-of-Discharge Voltage) algorithm and supports the Smart Battery System (SBS) 1.1 protocol for communication. Housed in a compact 30-TSSOP package, it is ideal for applications requiring precise battery state-of-charge (SOC) and state-of-health (SOH) reporting.
