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 ±3°C for multiple

transistor manufacturers, with no calibration needed. The

remote channel can also measure the die temperature of

other ICs, 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 format

is 7 bits plus sign, with each bit corresponding to 1°C, in

twos-complement format. Measurements can be done

automatically and autonomously, with the conversion 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

surface-mount package.
