SA56004X Block Diagram

SA56004X is an 11-bit remote/local digital temperature sensor that features SMBus 2.0 compatible interface and 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 degree Celsius is achieved.

Why Used

  • 8 different device addresses are available for server applications. The SA56004ED with marking code 56004E, and SA56004EDP with marking code 6004E are address compatible with the National LM86, the MAX6657/8 and the ADM1032.
  • Offset registers available for adjusting the remote temperature accuracy
  • Accurately senses temperature of remote microprocessor thermal diodes or diode connected transistors within +/-1 degree Celsius
  • Programmable under/overtemperature alarms: ALERT and T_CRIT
  • SMBus 2.0 compatible interface, supports TIMEOUT

Where Used

  • Electronic test equipment and instrumentation
