- Description The NXP Semiconductors SA56004X is an SMBus compatible, 11-bit remote/local digitaltemperature sensor with overtemperature alarms. The remote channel of the SA56004Xmonitors a diode junction, such as a substrate PNP of a microprocessor or a diodeconnected transistor such as the 2N3904 (NPN) or 2N3906 (PNP). With factory trimming,remote sensor accuracy of ±1 °C is achieved. Undertemperature and overtemperature alert thresholds can be programmed to cause theALERT output to indicate when the on-chip or remote temperature is out of range. Thisoutput may be used as a system interrupt or SMBus alert. The T_CRIT output is activatedwhen the on-chip or remote temperature measurement rises above the programmedT_CRIT threshold register value. This output may be used to activate a cooling fan, senda warning or trigger a system shutdown. To further enhance system reliability, theSA56004X employs an SMBus time-out protocol. The SA56004X has a unique devicearchitecture. The SA56004X is available in the SO8, TSSOP8 and HVSON8 packages. SA56004X has8 factory-programmed device address options. The SA56004X is pin-compatible with theLM86, MAX6657/8, and ADM1032.
