Desktop and Notebook Computers Smart Battery Packs LAN Servers Industrial Controls Central Office Telecom Equipment Test and Measurement Multi-Chip Modules Pin Configuration GENERAL DESCRIPTION
Remote accuracy is ±3°C for multiple transistor manufacturers, with no calibration needed. The 2-wire serial interface accepts standard System Management Bus (SMBusTM) Write Byte, Read Byte, Send Byte, and Receive Byte commands to program the alarm thresholds and to read temperature data. The data format is 7 bits plus sign, with each bit corresponding to 1°C, in two’s-complement format.
