MAX1617

Remote/Local Temperature Sensor

with SMBus Serial Interface

________________General Description

____________________________Features

The MAX1617 is a precise digital thermometer that

reports the temperature of both a remote sensor and its

own package. The remote sensor is a diode-connected

transistor—typically a low-cost, easily mounted 2N3904

NPN type—that replaces conventional thermistors or

thermocouples. Remote accuracy is 3ꢀ° for multiple

transistor manufacturers, with no calibration needed.

The remote channel can also measure the die tempera-

ture of other I°s, such as microprocessors, that contain

an on-chip, diode-connected transistor.

♦ Two Channels: Measures Both Remote and Local

Temperatures

♦ No Calibration Required

♦ SMBus 2-Wire Serial Interface

♦ Programmable Under/Overtemperature Alarms

♦ Supports SMBus Alert Response

♦ Accuracy:

2°C (+60°C to +100°C, local)

3°C (-40°C to +125°C, local)

3°C (+60°C to +100°C, remote)

The 2-wire serial interface accepts standard System

Management Bus (SMBus) Write Byte, Read Byte, Send

Byte, and Receive Byte commands to program the alarm

thresholds and to read temperature data. The data for-

mat is 7 bits plus sign, with each bit corresponding to

1ꢀ°, in twos-complement format. Measurements can be

done automatically and autonomously, with the conver-

sion rate programmed by the user or programmed to

operate in a single-shot mode. The adjustable rate allows

the user to control the supply-current drain.

♦ 3µA (typ) Standby Supply Current

♦ 70µA (max) Supply Current in Auto-Convert Mode

♦ +3V to +5.5V Supply Range

♦ Small, 16-Pin QSOP Package

The MAX1617 is available in a small, 16-pin QSOP sur-

face-mount package.
