MAX6689 Datasheet | Maxim Integrated

Description The MAX6689 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to six external diode-connected transistors. All temperature channels have programmable alert thresholds. Channels 1, 4, 5, and 6 also have programmable overtemperature thresholds. When the measured temperature of a channel exceeds the respective threshold, a status bit is set in one of the status registers. Two open-drain outputs, OVERT and ALERT, assert corresponding to these bits in the status register. 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 temperature data and programming the alarm thresholds. The MAX6689 is specified for an operating temperature range of -40°C to +125°C and is available in 20-pin QSOP and TSSOP packages. - - - - - - - - Features Six Thermal-Diode Inputs Local Temperature Sensor 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, 20-Pin QSOP and TSSOP Packages 2-Wire SMBus Interface Ordering Information PART MAX6689EP34+ MAX6689EP38+ MAX6689EP9A+ MAX6689EP9E+ MAX6689UP34+ MAX6689UP38+ MAX6689UP9A+ MAX6689UP9E+ PINPACKAGE 20 QSOP 20 QSOP 20 QSOP 20 QSOP 20 TSSOP 20 TSSOP 20 TSSOP 20 TSSOP SLAVE ADDRESS 0011 010 0011 100 1001 101 1001 111 0011 010 0011 100 1001 101 1001 111 PKG CODE E20-1 E20-1 E20-1 E20-1 U20-2 U20-2 U20-2 U20-2 Applications Desktop puters Notebook puters Workstations Servers SMBus is a trademark of Intel Corp.
