Working Principles
The TC646EOA713 operates by measuring the temperature difference between its two inputs (D+/-). This differential measurement technique provides accurate temperature sensing. Based on the sensed temperature, the IC adjusts the fan speed through the FAN pin. The temperature alarm output (ALERT) can be used to trigger an external alarm or shutdown mechanism when the temperature exceeds a user-defined threshold. The overtemperature shutdown input (OS) allows the system to be automatically shut down when the temperature reaches a critical level.
