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).
