Product Overview

The LM83CIMQA/NOPB is a Digital Temperature Sensor with a 2-wire serial interface that senses the voltage and thus the temperature of three remote diodes using a Delta-Sigma analogue-to-digital converter with a digital over-temperature detector. The device accurately senses its own temperature as well as the temperature of three external devices, such as Pentium II® Processors or diode connected 2N3904s. The temperature of any ASIC can be detected using the LM83 as long as a dedicated diode (semiconductor junction) is available on the die. Using the SMBus interface a host can access the LM83's registers at any time. Activation of a T_CRIT_A output occurs when any temperature is greater than a programmable comparator limit, T_CRIT. Activation of an INT output occurs when any temperature is greater than its corresponding programmable comparator HIGH limit. The host can program as well as read back the state of the T_CRIT register and the four T_HIGH registers.
  • Accurately senses die temperature of 3 remote ICs or diode junctions
  • On-board local temperature sensing
  • SMBus and I²C compatible interface, supports SMBus 1.1 TIMEOUT
  • Two interrupt outputs - INT\ and T_CRIT_A\
  • 7-bit Plus sign temperature data format, 1°C resolution
  • 2 Address select pins allow connection of 9 LM83s on a single bus
  • Green product and no Sb/Br
