5-Channel Precision Temperature Monitor

General Description

Features

♦ Four Thermal-Diode Inputs

♦ Local Temperature Sensor

The MAX6622 precision multichannel temperature sen-

sor monitors its own temperature and the temperatures

of up to four external diode-connected transistors. All

temperature channels have programmable alert thresh-

olds. Channels 1 and 4 also have programmable

overtemperature thresholds. When the measured tem-

perature of a channel exceeds the respective thresh-

old, a status bit is set in one of the status registers. Two

open-drain outputs, OVERT and ALERT, assert corre-

sponding to these bits in the status register.

♦ 1°C Remote Temperature Accuracy (+60°C to +100°C)

♦ Temperature Monitoring Begins at POR for Fail-

Safe System Protection

♦ ALERT and OVERT Outputs for Interrupts,

Throttling, and Shutdown

♦ STBY Input for Hardware Standby Mode

♦ Small, 16-Pin TSSOP Package

♦ 2-Wire SMBus Interface

The 2-wire serial interface supports the standard system

management bus (SMBus™) protocols: write byte, read

byte, send byte, and receive byte for reading the tem-

perature data and programming the alarm thresholds.

♦ Penryn CPU-Compatible

♦ Pin- and Register-Compatible with MAX6602

The MAX6622 is specified for a -40°C to +125°C oper-

ating temperature range and is available in a 16-pin

TSSOP package.
