MAX9940 - Signal-Line Overvoltage Protector

Description

28V Protection on EXT Extended ESD Protection ±4kV IEC 61000-4 Contact on EXT

Features

  • MAX9940 The MAX9940 signal-line overvoltage protector for lowvoltage digital communication ports provides protection against high-voltage faults and ESD strikes. The MAX9940 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. The MAX9940 operates from a single supply voltage of +2.2V to +5.5V and consumes only 13µA of quiescent supply current. The EXT.
