EMC1438

EMC1438 1°C Multiple Temperature Sensor with Hardware Controlled Standby & Hottest of Multiple Zones PRODUCT FEATURES Datasheet General Description The EMC1438 is a high accuracy, low cost, System Management Bus (SMBus) temperature sensor. Advanced features such as Resistance Error Correction (REC), Beta Compensation (to CPU diodes requiring the BJT or transistor model) and automatic diode type detection combine to provide a robust solution for complex environmental monitoring applications. Additionally, the hardware controlled STANDBY pin allows for system level power shutdown to support energy saving initiatives. The EMC1438 monitors up to eight temperature channels (up to seven external and one internal). The device provides ±1°C accuracy for the internal and external diode temperatures. Temperature monitoring includes two tiers of protection: one that can be masked and causes the ALERT pin to be asserted, and the other that cannot be masked and causes the THERM pin to be ass...
