BQ76952PFBR

BQ76952PFBR is the base version of a high-accuracy battery monitor and protector for packs of 3 to 16 cells, covering Li-ion, Li-polymer and LiFePO4 chemistries in a 7x7 mm TQFP-48 (PFB) package. It reports cell voltages, current and temperature to a host over I2C or SPI and operates from -40 C to +85 C. For pack designers, one monitor spanning up to 16 cells can serve product families from power tools to energy-storage modules, and the accurate measurement path supports tighter charge control and better state-of-charge estimation, which extends usable pack life and reduces warranty returns. Selection advice: this PFBR code is the base device whose protection settings are configured by the host system; the 01 to 04 orderable variants carry factory-programmed OTP configurations, so do not substitute them for the base code unless your firmware expects those pre-set thresholds. Match the full code, including the tape-and-reel R suffix, to your production process. Parameters verified against Texas Instruments documentation.
