General Description
The G768B contains a precise digital thermometer, 2 fan controllers, and a system-reset circuit.
The G768B is backward compatible with G768, Except that there is an additional watchdog function. This function prevents fan from being out of control when system fails.
The thermometer reports the temperature of 2 remote sensors and its own package. The remote sensors are diode-connected transistors typically a low-cost, easily mounted 2N3904 NPN type that replace conventional thermistors or thermocouples. Remote accuracy is ±5°C for multiple transistor manufacturers, with no calibration needed. The remote channel can also measure the die temperature of other ICs, such as microprocessors, that contain an on-chip, diode-connected transistor.
