Abstract

This document was translated from a simplified Chinese source. (ZHCAGC4)

The BQ76952 family of analog front ends (AFEs) is widely used in battery management system (BMS) solutions for various applications — such as BBUs, electric two-wheelers, power tools, and residential energy storage systems — owing to its high sampling accuracy, integrated high-side drivers, low power consumption, rich protection features, support for random power-up sequencing, compatibility with 3-16S batteries, and strong cell balancing capabilities. This paper introduces the short-circuit protection recovery mechanism of the BQ76952 based on internal configurations and proposes a method to achieve fast short-circuit recovery suitable for application scenarios with specific timing requirements for short-circuit recovery and hiccup mode operation.
