Maxim Integrated MAX4505

The MAX4505 is a single signal-line protector featuring a fault-protected input and Rail-to-Rail® signal handling capability. The input is protected from overvoltage faults up to ±36V with power on or ±40V with power off. This ensures an unambiguous rail-to-rail output when a fault begins and ends.

GENERAL DESCRIPTION

During a fault condition, the input terminal becomes an open circuit and only nanoamperes of leakage current flow from the source, while the switch output (AOUT) furnishes typically 19mA from the appropriate polarity supply to the load. The MAX4505 protects both unipolar and bipolar analog signals using either unipolar (+9V to +36V) or bipolar (±8V to ±18V) power supplies. The device has no logic control inputs; the protector is always on when the supplies are on. On-resistance is 100Ω max, and on-leakage is less than 0.5nA at TA = +25°C. The MAX4505 is available in 5-pin SOT23 and 8-pin µMAX packages.
