PRELIMINARY INFORMATION¹(SEELASTPAGE)

Quad Programmable Precision Supervisory Controller With Independent

Resets

FEATURES

INTRODUCTION

The SMS48 is a highly programmable voltage supply

controller and supervisory circuit designed specifically for

advancedsystemsthatneedtomonitormultiplevoltages.

TheSMS48canmonitorfourseparatevoltageswithoutthe

need of any external voltage divider circuitry. This allevi-

ates the need for factory-trimmed threshold voltages and

theuseofexternalcomponentstoaccommodatedifferent

supply voltages and tolerances.

z Operational from any of four Voltage Monitoring

Inputs

z FourIndependentProgrammableResetOutputs

z Programmability allows monitoring any voltage

between 0.6V and 5.6V with no external

components

z Programmable 5mV steps in the low range

z ProgrammableWatchdogTimer

z Programmable Reset Pulse Width

z FaultStatusRegister

The SMS48 has four programmable independant reset

outputstocontroldifferentdevicesforvaryingresetcondi-

tions such as UV, OV, watchdog and user pushbutton

applications.

APPLICATIONS

The SMS48 watchdog timer has a user programmable

time-out period and it can be placed in an idle mode for

system initialization or system debug. All of the functions

areuseraccessiblethroughanindustrystandardI²Cserial

interface.
