Products Detail

NCT7904D is a hardware monitor IC designed for high-end computer systems like servers and workstations. It monitors critical hardware parameters including power supply voltages, fan speeds, and temperatures using a 10-bit ADC. The device supports up to 20 voltage inputs, 12 fan tachometer inputs, 4 fan outputs, and 4 remote temperature sensor inputs (2 with current-mode capability). It features SMART FAN™ IV control with 4 temperature setpoints for optimized acoustic balance, PECI 1.0/2.0/3.0 interface for CPU temperature retrieval, and alarm outputs (SMI#, TEMP_ALM#, VOLT_ALM#, FAN_ALM#) for system protection. Additional functions include case-open detection, Watch Dog Timer, GPIO, and SMBus master for external sensor reading.
