MAX17617 Power Limiters

Analog Devices / Maxim Integrated MAX17617 Power Limiters provide programmable protection boundaries for systems against input voltage faults and output overcurrent faults. These power limiters protect against input-voltage faults up to 80V without reverse current protection and 75V with reverse current protection. This is achieved using the internal N-type Field Effect Transistor (nFET) featuring low ON-resistance of 20mΩ (typical). The MAX17617 power limiters feature a programmable Undervoltage-Lockout (UVLO) threshold by using external voltage dividers. These power limiters also feature a programmable Overvoltage-Lockout (OVLO) threshold and input-voltage reverse-polarity protection with an external nFET.
