Maxim has introduced overvoltage protection controllers that have an integrated battery disconnect switch with a current-limit range of 0,525 A to 1,1 A, depending on which part is used. The MAX4880-MAX4884 have an integrated current-limit switch in a 3 x 3 mm TDFN package, and provide overvoltage protection to +28 V. Trip levels range from 4,5 V to 5,6 V, and undervoltage trip levels range from 2,55 V to 4,35 V. Additional features include flag signals (overvoltage, overcurrent, battery voltage trip) and an internal charge pump. Also featured are thermal shutdown protection, 15 kV ESD protection, and a built-in start-up delay that allows the adapter voltage to settle down before turning on the external MOSFET. The MAX4880 can also be configured as a low-cost battery charger.
