DS1780E+

The DS1780E+ is a CPU peripheral monitor in 24 pin TSSOP package. This highly integrated system instrumentation monitor is ideal for use in personal computers or any microprocessor based system. It monitors ambient temperature, six power supply voltages and speed of two fans. Fan speed can also be controlled with the use of an internal 8bit DAC. All measurements are internally converted to a digital format for easy processing 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 has an interrupt that can be programmed to become active when any of functions monitoring by DS1780 falls out of specification. For board level testability, an internal NAND TREE function simplifies the system design. A chassis intrusion input is featured to enhance system security. The DS1780 power supply range from 2.8V to 5.75V allows for monitoring of parameters for 3V or 5V systems.

• Direct to digital temperature sensor requires no external components or user calibration
• Two fan speed sensors
• Programming and data readout are accessed via a simple 2-wire interface with 2bit addressability
• 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
