MAX6693

19-4096; Rev 0; 5/08 www.DataSheet4U.com 7-Channel Precision Temperature Monitor with Beta Compensation General Description The MAX6693 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 MAX6693 is specified for an operating temperature range of -40°C to +125°C and is available in a 20-pin TSSOP package. ♦ Six Thermal-Diode Inputs ♦ Beta Compensation (Channel 1) ♦ Local Temperature Sensor ♦ 1.5°C Remote Temperature Accuracy (+60°C to +100°C) ♦ Temperature Monitoring Begins at POR for FailSafe System Protection ♦ ALERT and OVERT Outputs for Interrupts, Throttling, and Shutdown ♦ STBY Input for Hardware Standby Mode ♦ Small, 20-Pin TSSOP Package ♦ 2-Wire SMBus Interface Features MAX6693 Ordering Information PART MAX6693UP9A+ TEMP RANGE -40°C to +125°C PIN-PACKAGE 20 TSSOP Applications Desktop Computers Noteboo...
