FEATURES
§ Direct-to-digital temperature sensor requires
no external components or user calibration
§ Two fan speed sensors
§ Monitors 6 power supply voltages
§ 8-bit DAC for fan speed control
§ Intrusion detect for security (detects when
chassis lid has been removed, even if power is
off)
§ Remote system reset
§ System interrupt availability on all monitored
functions (temperature, voltages, fan speed,
chassis intrusion)
§ 2-wire interface with 2-bit addressability
§ Integrated NAND TREE for board level
testability
§ Wide power supply range (2.8V £ V DD £
5.75V)
§ High integration in a small 24-pin 173-mil
TSSOP
§ Applications include monitoring of personal
computers or any microprocessor-based
system
