The CXFA3160 contains 3 precise digital thermometers, one fan controllers, hardware and software thermal shutdown. The thermometers report the temperature of 3 remote sensors. The remote sensors are diode-connected transistors typically a low-cost, easily mounted 2N3904 NPN type or the diode built-in in CPU. Remote accuracy is ±1°C for multiple transistor manufacturer. The CXFA3160 also support offset adjust function via SMBus to fix the error due to different CPU diode or parasitic resistors. The 2-wire serial interface accepts standard System Management Bus (SMBusTM) Write Byte, Read Byte, Send Byte, and Receive Byte commands. CXFA3160 SMBus address is 7ah for write and 7bh for read. And supports writting protection function by command 20h to prevent error behavior of μP. CXFA3160 contains one PWM mode fan controllers. FAN controller performs closed-loop and open-loop control. CXFA3160determines the current fan speed based on the FG inputs and an externally supplied 32.768kHz clock. CXFA3160also provide ALERT for fan fail and out of control event. The CXFA3160provides hardware and software thermal shutdown. The hardware thermal shutdown is for the sensor 2. The trigger point is set external resistors. The trigger points of software thermal shutdown are set via SMBus. If thermal shutdown event occurs, THERM pin outputs low
