ML5238 Overview
The ML5238 is analog front end IC for 16 series Lithium Ion secondary battery pack protection system. The ML5238 provides the function of cell voltage monitoring, charge/discharge current monitoring function, and it can detect over-charge/over-discharge of each battery cell charge/discharge over-current. The ML5238 has short current detecting function which can turn off the external charge/discharge MOS-FET without...
