General Description

BL15721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3) applications.

The BL15721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master.

The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers.
