Overview
19-1415; Rev 1; 8/99 Fault-Protected, High-Voltage Signal-Line Protectors General Description The MAX4506/MAX4507 multiple, two-terminal signal-line protectors are pin-compatible with the industry-standard MAX366/MAX367.
These new circuit protectors feature fault-protected inputs and Rail-to-Rail® signal handling capability.
The input pins are protected from overvoltage faults up to ±36V with power on or ±40V with power off.
During a fault condition, the input terminal becomes an open circuit and only nanoamperes of leakage current flow from the source; but the switch output (OUT_) furnishes typically 19mA from the appropriate polarity supply to the load.
This ensures unambiguous rail-to-rail outputs when a fault begins and ends.
The MAX4506 contains three independent protectors while the MAX4507 contains eight independent protectors.
They can protect both unipolar and bipolar analog signals using either unipolar (+9V to +36V) or bipolar (±8V to ±18V) power supplies.
These devices have no logic control inputs; the protectors are designed to be always-on when the supplies are on.
On-resistance is 100Ω max and matched within 7Ω, and on-leakage is less than 0.
5nA at TA = +25°C.
The MAX4506 is available in 8-pin SO/DIP packages.
The MAX4507 is available in 20-pin SSOP and 18-pin SO/DIP packages.
