MAX16126TCA+

The MAX16126TCA+ 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. It has a flag output that asserts during fault conditions. For reverse-voltage protection, external back to back MOSFETs outperform the reverse-battery diode, minimizing the voltage drop and power dissipation during normal operation. It provides switch-mode fault management available in 4 options such as latch mode, 1 autoretry mode, 3 autoretry mode & always autoretry mode.

• Supply voltage range is 3V to 30V
• Operating temperature range from -40°C to 125°C
• Adjustable overvoltage and undervoltage comparator thresholds
• Limiter mode fault management for overvoltage and thermal shutdown conditions
• Wide input voltage protection range from -36V to +90V
• Supply current is 350μA (max) and shutdown current is 100μA (max) at 30V input
