MAX1617A

Remote/Local Temperature Sensor

with SMBus Serial Interface

________________General Description

____________________________Features

The MAX1617A 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 ther-

mocouples. Remote accuracy is 3ꢀ° for multiple transis-

tor manufacturers, with no calibration needed. The remote

channel can also measure the die temperature 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

♦ Supports Manufacturer and Device ID Codes

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 1ꢀ°, in

two’s 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.

♦ 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)

♦ 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 MAX1617A is nearly identical to the popular MAX1617,

but has improved SMBus timing specifications, improved

bus collision immunity, software manufacturer and device

identification available via the serial interface, and a power-

on reset function that can force a reset of the slave address

via the serial interface.
