MAX9940

The MAX9940 is designed as one kind of signal-line overvoltage protector device that can be used in (1)notebook computers; (2)portable devices; (3)industrial equipment applications. And this device is especially useful for sensitive communication protocols such as Maxim 1-Wire that cannot afford standard means of fault protection, such as large series resistors or large line capacitances.

Features of the MAX9940 are:(1)28V Protection on EXT; (2)Extended ESD Protection +/-4kV IEC 61000-4 Contact on EXT; (3)+2.2V to +5.5V Supply Voltage Range; (4)13 uA Quiescent Supply Current; (5)60ns Fault Reaction Time; (6)Small, 5-Pin SC70; (7)-40 to +125 Temperature Range.

The absolute maximum ratings of the MAX9940 can be summarized as:(1)Storage Temperature Range: -65°C to +150°C;(2)Junction Temperature: +150°C;(3)Operating Temperature Range: -40°C to +125°C;(4)Continuous Power Dissipation (TA = +70°C): 245 mW;(5)Continuous Input Current into Any Terminal: ±20 mA;(6)EXT: -0.3V to +30V;(7)INT: -0.3V to +6V;(8)VCC: -0.3V to +6V.
