CPU Peripheral Monitor
DS1780
072898 1/28
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 func-
tions (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
≤

DESCRIPTION
The DS1780 is a highly integrated system instrumenta-
tion monitor ideal for use in personal computers, or any
microprocessor–based system. It monitors ambient
temperature, six power supply voltages, and the speed
of two fans. Fan speed can also be controlled with the
use of an internal 8–bit DAC. All measurements are
internally converted to a digital format for easy proces-
sing by the CPU.
The DS1780 can be reset to its default power up state
via a remote reset function with internal debounce and
delay. It features an interrupt that can be programmed
to become active should any of the functions the
DS1780 is monitoring fall out of spec.
