Overview
The BQ76952 is a highly integrated, high-precision battery monitor and protector for 3-series to 16-series lithium-ion, lithium polymer, and LiFePO4 battery packs. The device includes a high-precision monitoring system and a highly configurable protection subsystem, with support for autonomous or host-controlled cell balancing. It integrates a high-side charge pump NFET driver, dual programmable LDOs for external system use, and a host communication peripheral supporting 400kHz I2C, SPI, and HDQ single-wire standards. The BQ76952 is available in a 48-pin TQFP package.
