NXP NE1617A Temperature Monitor Datasheet

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.

About this manual

The NXP NE1617A is an accurate two-channel temperature monitor designed for microprocessor systems. It measures the temperature of itself (local sensor) and a remote sensor, which is typically a diode-connected transistor like the 2N3904 or built into Intel microprocessors. Both temperatures are stored in a register readable via a 2-wire SMBus interface.
