MAX4880 Overview
Description
The MAX4880 is an overvoltage-protection controller with an internal current-limited switch that can be configured as a low-cost battery charger. When the input voltage exceeds the overvoltage trip level (5.7V), or drops below the undervoltage-lockout level (4.2V), the MAX4880 turns off the external n-channel MOSFET and asserts an undervoltage/overvoltage flag indicator (FLAGV) low to notify the processor.
