The MAX16128/MAX16129 load-dump/reverse-voltageprotection circuits protect power supplies from damaginginput-voltage conditions, including overvoltage,reverse-voltage, and high-voltage transient pulses. Usinga built-in charge pump, the devices control two externalback-to-back n-channel MOSFETs that turn off and isolatedownstream power supplies during damaging inputconditions, such as an automotive load-dump pulse or areverse-battery condition. Operation is guaranteed downto 3V that ensures proper operation during automotivecold-crank conditions. These devices feature a flag output(FLAG) that asserts during fault conditions.
