LM84CIMQA Description

Short technical summary and product information.

The LM84CIMQA is a diode input digital temperature sensor featuring a two-wire SMBus interface. It is designed to sense its own temperature as well as the temperature of a target IC with a diode junction, making it suitable for system thermal management applications.

 

Key electrical specifications include a supply voltage range of 3.0V to 3.6V and a maximum supply current of 1 mA. The sensor provides local temperature accuracy of ±1.0°C (typical) and remote diode temperature accuracy of ±3°C (max) between +60°C and +100°C, and ±5°C (max) between 0°C and +125°C.

 

The LM84CIMQA supports SMBus Timeout and has register readback capability. It utilizes a 7-bit plus sign temperature data format. Two address select lines allow up to nine LM84 devices to be connected to a single bus.

 

This component is available in a QSOP-16 package. It is supplied in quantities of 95 units per rail or 2500 units on tape and reel.
