FMS2701  
Temperature and Power Supply Voltage Monitor  
Features  
Description  
• Remote diode temperature sensing  
• Ambient (on-chip) temperature sense  
• Dual 3.3 volt supply monitoring  
• SMBus interface to internal registers  
• Status registers  
The FMS2701 is a temperature- and voltage-monitoring  
device that can be interrogated and controlled through an  
SMBus serial interface. Outputs are an analog fan control  
voltage, thermal alarm and interrupts.  
• Thermal trip output  
• Interrupt output  
• Fan speed control output  
• ACPI Thermal Management compliant  
Remote (DIODE+ and DIODE-) and ambient diode temper-  
ature sensor inputs are selected in sequence at a 1Hz rate by  
a multiplexer that drives an A/D converter. Digitized diode  
temperatures are stored in registers. Violation of a program-  
mable limit or trip point will set an interrupt register bit and/  
or assert a digital output.  
Applications  
Power supply voltages are monitored through two pins:  
VCCAUX3 monitors the power to the FMC2701; VCC3 is a  
separate 3.3 volt sense voltage input. AUXRST and RST out-  
puts indicate the status of voltage monitoring.  
• PCs and Servers, Workstations  
• Office Equipment  
• Test and Measurement Instruments  
Analog output, FAN_SPD can be used as an input to a fan  
speed control circuit while THERM, INT and FAN_OFF are  
additional digital control outputs.  
Power is derived from a +3.3V supply. Package is 16-lead  
Quad Small Outline Pack (QSOP).
