GENERAL DESCRIPTION
●The NE1619 is designed for monitoring the temperatures and supply voltages of microprocessor-based systems by measuring those parameters and comparing the readings with programmable limits. The device provides five possible analog inputs, a remote temperature sensor input and on-board local temperature sensor. The device also monitors its own power supply and provides digital inputs for the Pentium/PRO power supply ID code.
