 Description

The DIA1413/1414 are high-precision sensor chips

for temperature monitoring in automotive

sub-systems. The DIA1413/1414 achieve 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 DIA1413 monitors three temperatures channels.

And the DIA1414 monitors four temperature channels.

The DIA1413/1414 are compatible with the System

Management Bus (SMBus) and Inter-Integrated

Circuit (I2C) communication protocol.

The DIA1413/1414 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.

 Applications

 Automotive ADAS system

 Automotive infotainment system

 Processor temperature monitoring
