MAX16127TC+T

The MAX16127TC+T is a load dump/reverse voltage protection circuit in 12 pin TQFN package. The load-dump/reverse voltage protection circuits protect power supplies from damaging input voltage conditions including overvoltage, reverse voltage and high voltage transient pulses. Using a built-in charge pump, the device controls two external back to back N-channel MOSFETs that turn off and isolate downstreams power supplies during damaging input conditions such as an automotive load dump pulse or a reverse battery condition. Operates down to 3V to ensure proper operation during automotive cold-crank conditions. The device feature a flag output that asserts during fault conditions. For reverse voltage protection, external back to back MOSFETs outperform the traditional reverse battery diode, minimizing the voltage drop and power dissipation during normal operation. The MAX16127 provides limiter mode fault management for overvoltage and thermal shutdown conditions.
