Overview
19-3304; Rev 0; 5/04 SMBus-Compatible Temperature Monitor with Automatic PWM Fan-Speed Controller General Description The MAX6641 temperature sensor and fan controller accurately measures the temperature of its own die and the temperature of a remote pn junction.
The device reports temperature values in digital form using a 2-wire serial interface.
The remote pn junction is typically the emitter-base junction of a common-collector pnp on a CPU, FPGA, or ASIC.
The 2-wire serial interface accepts standard System Management Bus (SMBus) TM write byte, read byte, send byte, and receive byte commands to read the temperature data and program the alarm thresholds.
The temperature data controls a PW...
