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

PowerSO-36

PowerSSO-36

for the physical layer, the Network Controller and

the External Host Controller of a MOST Node.

The L5961 also allows the implementation of a

generic MOST node design that can be

reproduced "as is" in any other project, thus

avoiding the activities of redesign and re-

verification of MOST PMD compliance

The L5961 implements complete monitoring of

the supply voltage (over-voltage, under-voltage,

critical voltage), moreover it supports multiple

power modes like Zeropower-mode (where one

complete MOST node sinks around 25µA current)

and Ultra-zero power mode (5µA). All the

diagnostic protocols from major carmakers are

supported and the device reacts to many different

wake-up events.

The L5961 is completely configurable through its

I2C bus and fully compatible with MOST

specifications.

L5961 has been specified in cooperation with

SMSC and represents a "chipset" solution when

used with SMSC's MOST network interface

controllers (INIC or NIC).
