DS1780E Description

Short technical summary and product information.

The DS1780E from Analog Devices is a versatile system instrumentation monitor designed for microprocessor-based systems like personal computers. It offers direct-to-digital temperature sensing without external components, monitors up to six power supply voltages, and tracks the speed of two fans. Fan speed control is also available via an integrated 8-bit DAC.

 

This device features a chassis intrusion detection input for enhanced security and a remote system reset function. System interrupts can be programmed for all monitored functions, including temperature, voltages, fan speed, and chassis intrusion. Data is accessed and programmed through a simple 2-wire interface with 2-bit addressability.

 

The DS1780E operates within a wide power supply range of 2.8V to 5.75V, making it suitable for both 3V and 5V systems. It is housed in a compact 24-pin TSSOP package with a surface mount type, measuring 173-mil wide. The operating temperature range is -40°C to 125°C.
