Description
The L5961 MOST PMD integrates all the discrete circuitry usually necessary to implement power supplies and power management for a MOST node. It includes intrinsic MOST specific power management together with sophisticated diagnostic and fail-safe functions. The MOST PMD is designed to provide direct power supply for the physical layer, the Network Controller and the External Host Controller of a MOST Node.
