MAXIM MAX17526AATP+T

The Olympus series of ICs are the smallest and robust integrated system protection solutions. The MAX17526A adjustable power limiter offers a unique feature to limit power drawn from supplies or delivered to loads, amongst a host of protection features. These protection features include adjustable input overvoltage and undervoltage protection, positive and negative input voltage protection, overcurrent protection, reverse-current protection and overtemperature protection. The device features a built-in low RON (30mΩ typ) NFET, and an integrated gate drive for an optional external NFET.
