DS1780 Product details

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 output VOUT/NTIN - DAC output / NAND TREE Input RST - Remote System Reset GNDA - Analog Ground +xxVIN +2.5VS/+VCCP2 - Positive Voltage Inputs - Positive/negative Voltage Input VIDx - Processor V

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.
