19-3776; Rev 0; 7, 05 Overvoltage-Protection Controller with Internal Disconnect Switch General 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 no
