BQ7791504PW TI Battery Protection IC | 24-TSSOP | 4-5S Li-Ion, OVP/UVP/OCD/SCD

Product Overview

The BQ7791504PW from Texas Instruments is a highly integrated, secondary protection IC for 4- to 5-series Li-Ion and Li-Polymer battery packs. It provides overvoltage protection (OVP), undervoltage protection (UVP), overcurrent discharge protection (OCD), and short-circuit discharge protection (SCD). The device operates with a low power consumption of typically 1 µA in normal mode and 0.1 µA in shutdown mode. Packaged in a 24-TSSOP, it is designed for space-constrained applications requiring robust battery safety.
