Interface chip, first to pass PSI5 specification V1.3

Conducted by an external test lab recommended by the PSI5 consortium, the E981.08 interface chip is now available from Gleichmann Electronics. PSI5 is an open standard for bidirectional digital sensors and, with PSI5-P, PSI5-U and PSI5-D, the E981.08 is designed to support all of the applicable topologies described in the specification. It provides four independent channels through which up to three distributed sensors can each be connected to a microcontroller. Each channel supplies the sensor devices, connected via a two wire line, with a regulated dc voltage. The bidirectional communication between microcontroller and sensors takes place by means of current or voltage modulation also via the two wire line. The maximum transmission rate of 125Kbit/s is between that in LIN networks and CAN networks by comparatively lower wiring expenditure.
