DIO1414

The DIO1414 is a high-precision sensor chip for temperature monitoring in laptops, servers, and industrial applications. The DIO1414 achieves an inaccuracy of ±1°C even in complex application environments by utilizing advanced methods, including Resistance Error Correction (REC), Dynamic Element Matching, Automatic BJT Type Detection and Automatic Beta Detection and Compensation. The DIO1414 monitors four temperature channels. The DIO1414 is compatible with the System Management Bus (SMBus) and Inter-Integrated Circuit (I2C) communication protocol. The DIO1414 can operate at ambient temperatures of -40°C ~ 125°C and have programmable High, Low, and Therm Limit for over-temperature alarm. In addition, the device can also detect erroneous states.
