SA56004x Overview
The NXP Semiconductors SA56004X is an SMBus patible, 11-bit remote/local digital temperature sensor with overtemperature alarms. The remote channel of the SA56004X monitors a diode junction, such as a substrate PNP of a microprocessor or a diode connected transistor such as the 2N3904 (NPN) or 2N3906 (PNP). With factory trimming, remote sensor accuracy of 1 C is achieved.
SA56004x Key Features
- Accurately senses temperature of remote microprocessor thermal diodes or diode connected transistors within 1 C
- On-chip local temperature sensing within 2 C
- Temperature range of 40 C to +125 C
- 11-bit, 0.125 C resolution
- 8 different device addresses are available for server
SA56004x Applications
- Offset registers available for adjusting the remote temperature accuracy
