Analog Devices Inc. MAX17526x 6A Current Limiters

Analog Devices Inc. MAX17526x 6A Current Limiters are adjustable power limiters that offer 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 MAX17526 features a built-in low RON (30mΩ typical) NFET and an integrated gate drive for an optional external NFET.

The Analog Devices MAX17526x 6A Current Limiters are available in a 5mm x 5mm TQFN20 package with an exposed pad for enhanced thermal performance. The devices operate over a -40°C to +125°C extended temperature range.
