1 / 34 page  DIA1412 Version 1.0, Jul 2024 www.dioo.com © 2024 DIOO MICROCIRCUITS CO., LTD. I Multiple Channel ±1°C Temperature Sensor with Beta Compensation Features AEC-Q100 qualified: − Device ambient temperature: -40°C ≤ TA ≤ 125°C − Device junction temperature: -40°C ≤ TJ ≤ 150°C Wide supply voltage range: 3.0 V to 3.6 V One external diode temperature monitor − Maximum inaccuracy of ±1°C (20 ~ 110°C) − 12-bit resolution: 0.0625°C One internal diode temperature monitor − Maximum inaccuracy of ±1°C (20 ~ 110°C) − 12-bit resolution: 0.0625°C Resistance Error Correction Automatic BJT Type Detection Programmable High Limit and Low Limit ( _____ ALERT pin) Programmable Therm Limit ( ______ THERM/ADDR pin) Programmable SMBus (or I2C) address − 1001_100(r/ _ w): DIA1412A − Selectable by ______ THERM /ADDR pull-up resistance: DIA1412C Applications Automotive ADAS system Automotive infotainment system Processor temperature monitoring Package Information Description The DIA1412 is a high-precision sensor chip for temperature monitoring in automotive sub-systems. The DIA1412 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, Automatic Beta Detection, and Compensation. The DIA1412 monitors one external diode temperature and one internal diode temperature. The DIA1412 is compatible with the System Management Bus (SMBus) and Inter-Integrated Circuit (I2C) communication protocol. The DIA1412 can operate at ambient temperatures of -40°C ~ 125°C and have programmable High, Low, and Therm Limit for overtemperature alarm. In addition, the device can also detect erroneous states.
