Features
- Measures Two Remote and One Local Temperatures
- Adjustable Offset for Each Sensor via SMBus
- Accuracy: Remote ±1°C ( 20°C to 80°C) ±3°C (-10°C to 120°C) 4.5V to 5.5V Supply Range
- Alert Signal for Diode Fault, Fan Fail, and Fan Out of Control
- Supports SMBus Alert Response
- Fan Drivers Using Linear Control Algorithm
- Closed Loop Speed Control and programmable 8 Bits Open Loop Voltage Control for Fan
- Wide speed control range for Fan, Accuracy within 2%, when FANx_SET_CNT > 50

General Description
The G7931/G7932 contains 3 precise digital thermometers, 3/4 fan controllers, fan failure detection. The thermometers report the temperature of 2 remote sensors and 1 local sensor. 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.

Local accuracy is ±3°C. The G7931/G7932 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. The SMBus address is 70h 72h for write and 7173hh for read for G7932.For G7931, ADD0 pin selects 3 different SMBus addresses. (see ? SMBus Digital Interface? section) G7931/G7932 contains 3/4 fan controllers which perform closed-loop and open-loop control.

G7931/ G7932 determines the current fan speed based on the FG inputs and an externally supplied 32.768kHz clock. The driving ability is 5mA. G7931/G7932 also provides ALERT for fan fail and out of control event.
