LTC2991

Octal I C Voltage, Current,

and Temperature Monitor

FEATURES

DESCRIPTION

The LTC^®2991 is used to monitor system temperatures,

Measures Voltage, Current, Temperature

Measures Four Remote Diode Temperatures

voltagesandcurrents.ThroughtheI Cserialinterface,the

0.7°C (Typ) Accuracy, 0.06°C Resolution

eight monitors can individually measure supply voltages

and can be paired for differential measurements of cur-

rent sense resistors or temperature sensing transistors.

Additional measurements include internal temperature

1°C (Typ) Internal Temperature Sensor

Series Resistance Cancellation

14-Bit ADC Measures Voltage/Current

PWM Temperature Output

and internal V . The internal 10ppm reference minimizes

3V to 5.5V Supply Operating Voltage

the number of supporting components and area required.

Selectable address and configurable functionality give the

LTC2991 flexibility to be incorporated in various systems

needingtemperature,voltageorcurrentdata.TheLTC2991

fitswellinsystemsneedingsubmillivoltvoltageresolution,

1% current measurement and 1°C temperature accuracy

or any combination of the three.

Eight Selectable Addresses

Internal 10ppm/°C Voltage Reference

V1 to V8 Inputs ESD Rated to 6kV HBM
