    PDF, 1.8 Mb, File published: Dec 5, 2016
    The BQ77905 is a 3-5S low-power protector for lithium-ion batteries that controls the charge anddischarge FETs for current control. In some cases, the charge and discharge current path is required tohandle a continuous high-current that causes heat and component problems. This document provides anexample of the BQ77905 with a 50-A current path for charge and discharge. The design considerati
