Interfacing high-voltage applications to low-power controllers

December 14, 2011 // By Thomas Kugelstadt, TI
A common requirement of industrial applications is to interface high-voltage potentials, such as signal outputs of sensor switches and AC rectifiers, to the peripheral input ports of low-voltage MCUs and DSPs. A new generation of interface circuits providing this function are digital-input serializer (DIS) devices. This paper explains the functional principle of a DIS and its configuration in a typical industrial interface design.
