MAXIM INTEGRATED / ANALOG DEVICES MAX16129UAAGA+ Datasheet & Stock

The MAX16129UAAGA+ from Maxim Integrated Products is a load dump/reverse voltage protection circuit in 8 pin µMAX package. It protects 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 isolates downstream power supplies during damaging input conditions such as an automotive load-dump pulse or a reverse-battery condition. Operation is down to 3V that ensures proper operation during automotive cold-crank conditions. Features a flag output that asserts during fault conditions. For reverse-voltage protection, external back to back MOSFETs out perform the traditional reverse-battery diode, minimizing the voltage drop and power dissipation during normal operation. The device uses fixed overvoltage and undervoltage thresholds, minimizing the external component count.
