SA56004ADP,118

SA56004ADP,118 is a SMBus-compatible, 8-pin, remote/local digital temperature sensor with overtemperature alarms. It is an SMBus-compatible, 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. Under temperature and overtemperature, alert thresholds can be programmed to cause the (active-low) ALERT 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 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.

• Accurately senses temperature of remote MPU thermal diodes or diode connected transistor within ±1°C
• On-chip local temperature sensing within ±2°C
• Programmable under/overtemperature alarms: ALERT (active low) and T-CRIT (active low)
• SMBus 2.0 compatible interface, supports TIMEOUT
• I²C-bus standard-mode and fast-mode compatible
• Programmable conversion rate (0.0625Hz to 26Hz)
• Undervoltage lockout prevents erroneous temperature readings
• Latch-up testing is done to JEDEC Standard JESD78 which exceeds 100mA
• TSSOP8 package, ambient temperature range from -40 to +125°C
