BQ76925PW TI Battery Monitor | 20-TSSOP | 3-6S, I2C, 1mA

Product Overview

The BQ76925PW is a high-performance battery monitor and protector IC from Texas Instruments, designed for 3- to 6-series cell Li-ion, Li-Polymer, and LiFePO4 battery packs. It integrates a precision analog-to-digital converter (ADC) for voltage, current, and temperature measurement, along with a programmable protection engine. Housed in a compact 20-TSSOP package, it enables accurate state-of-charge (SoC) and state-of-health (SoH) monitoring in space-constrained applications.

Detailed Technical Specifications

Key Features

• Integrated 14-bit voltage ADC and 16-bit current ADC for high-accuracy monitoring
