NE1619
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.
The device communicates with the system controller via an SMBus
(System Management bus) by which it can be programmed for
operation and data collection. Readings come from conversions of
the on-board A-to-D converter which cycles through all
measurements in sequence in approximately one second when the
conversion is started. The device includes a number of registers to
store data of the device configuration, status, readings and limits.
Except for the temperature-related data which are in 8-bit digital
2’s complement format, all the data are in 8-bit digital straight format.
FEATURES

FUNCTION DESCRIPTION
Digital I/O. SMBus serial bi-directional data. Open-drain output.
Digital Input. SMBus serial clock input.
Ground. To be connected to system ground.
Power supply. Can be connected to +3.3 V standby power if monitoring in low power states is
required. This pin also serves as the analog input to monitor the VDD voltage level.
Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status
register (LSB bit).
Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.
Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.
Digital Input. For Voltage ID readouts from the processor. This value is read into the VID status register.
Analog/Digital Input. This pin is connected to the negative terminal of the remote temperature sensor for
analog input. If this pin is held high at power-up, for digital input, it enables the NAND-TREE test mode.
Analog Input. This pin is connected to the positive terminal of the remote temperature sensor.
Analog/Digital Input. Defaults at power-up to analog input for monitoring the +12 V supply. This pin is
programmable to be a digital input for voltage ID readouts from the processor. Its state is read into
the VID4 status register.
Analog Input. For monitoring the +5 V supply.
Analog Input. For monitoring the +3.3 V supply.
Analog Input. For monitoring the +2.5 V supply.
Analog Input. For monitoring the processor voltage supply (0 to 3.0 V)
Digital I/O. At power-up, the logic input of this pin defines the LSB bit of the device slave address.
This pin can be configured to give a low pulse reset output of 20ms minimum. This pin also functions
as the output in the NAND–TREE test mode.
