DS1780 - CPU Peripheral Monitor

Description

A0/NTOUT TREE - Address Input / NAND Output A1 - Address Input SDA - 2-Wire Serial Data Input/Output SCL - 2-Wire Serial Clock FANx - Tachometer Inputs CHS - Chassis Intrusion Detector Input GNDD - Digital Ground VDD - Power Supply Voltage (2.8V to 5.75V) INT - Hardware Interrupt out

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.
