NE1617ADS Dettagli del prodotto

General description
The NE1617A is an accurate two-channel temperature monitor. It measures the temperature of itself and the temperature of a remote sensor. The remote sensor is a diode connected transistor. This can be in the form of either a discrete NPN/PNP, such as the 2N3904/2N3906, or a diode connected PNP built into another die, such as is done on some Intel microprocessors.
The temperature of both the remote and local sensors is stored in a register that can be read via a 2-wire SMBus. The temperatures are updated at a rate that is programmable via the SMBus (the average supply current is dependent upon the update rate — the faster the rate, the higher the current).
In addition to the normal operation, which is to update the temperature at the programmed rate, there is a one-shot mode that will force a temperature update.
There is also an alarm that senses either an overtemperature or undertemperature condition. The trip points for this alarm are also programmable.
The device can have one of nine addresses (determined by two address pins), so there can be up to nine of the NE1617A on the SMBus.
It can also be put in standby mode (in order to save power). This can be done either with software (over the SMBus) or with hardware (using the STBY pin).
