The MAX16127TC+ 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 devices control two external back to back n-channel MOSFETs that turn off and isolate downstream 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.
