SA56004CDP,118

SA56004CDP,118 is a SMBus-compatible, 8-pin, remote/local digital temperature sensor with overtemperature alarms. The remote channel of the device 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. Undertemperature and overtemperature alert thresholds can be programmed to cause the ALERT (active low) output to indicate when the on-chip or remote temperature is out of range. This output may be used as a system interrupt or SMBus alert. The T_CRIT (active low) output is activated when the on-chip or remote temperature measurement rises above the programmed T_CRIT threshold register value. Application includes system thermal management in laptops, desktops, servers and workstations, computers and office electronic equipment, electronic test equipment and instrumentation, HVAC, industrial controllers and embedded systems.
