The MAX1617 (patents pending) 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 con-

ventional thermistors or thermocouples. Remote accu-

racy 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-con-

nected 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 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.
