L5961

MOST power management device (PMD)

Data Brief

Features

■ 5V or 3.3V / 650mA DC-DC Converter with

external sync

■ 5V or 3.3V/ 40mA standby voltage regulator

■ 5V or 3.3V / 60mA switchable voltage regulator

PowerSO-36

■ Very low quiescent current (zero power mode

and ultra zero power mode feature)

■ Power management fully compatible to MOST

PowerSSO-36

specification

■ Provides power supply for physical layer and

for the physical layer, the Network Controller and

the External Host Controller of a MOST Node.

control unit

■ Switch to power pulse generator

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

■ Reacts on four different wake-up events

–

Switch to power pulse (STPP)

Light ON (for status)

Activity on Diagnostic_I/O

ON/OFF switch

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.

■ I C interface

■ Programmable system configuration

■ Reset generator

■ Intrinsic diagnostic transceiver

(standard LIN2.0)

■ 3 battery detectors for battery voltage

monitoring

The L5961 is completely configurable through its

■ Watchdog circuit

I C bus and fully compatible with MOST

specifications.

■ PowerSS0-36 and PowerSO-36 packages

options

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).

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
