Signal-Line Overvoltage Protector For Low-Voltage Devices

The MAX9940 signal-line overvoltage protector for low- voltage digital Communication ports provides protection against High-Voltage faults and ESD strikes. The MAX9940 is especially useful for sensitive communica- tion protocols such as Maxim 1-Wire® that cannot afford standard means of fault protection, such as large series resistors or large line capacitances. The MAX9940 operates from a single supply voltage of +2.2V to +5.5V and consumes only 13µA of quiescent supply current. The EXT port is protected up to 28V. The device features a reaction time of 60ns for fast action during fault conditions and operates over the -40°C to +125°C automotive temperature range. By Maxim Integrated Products
