NCT7904D Description

Short technical summary and product information.

The Nuvoton NCT7904D is an advanced hardware monitoring IC from the Nuvoton Hardware Monitoring IC family. It provides precise voltage and temperature monitoring capabilities, essential for system stability and performance.

 

This IC features an internal 10-bit ADC that converts monitored temperature with an accuracy of ±1°C. It supports monitoring up to 5 temperature channels and 20 analog voltage inputs simultaneously. The NCT7904D can retrieve CPU temperature information directly via the Intel® PECI3.0 interface or AMD SB-TSI interface. For fan control, it can monitor up to 12 fan tachometer inputs and control 4 fan outputs in DC or PWM mode.

 

The NCT7904D includes a range of system alert features such as PROCESSOR HOT detection, Case-open detection, and Watch Dog Timer functions. Alarm signals include SMI#, TEMP_ALM#, VOLT_ALM#, and FAN_ALM#, with configurable threshold values for immediate system protection.

 

Packaged in a 48-LQFP (7x7) format, the NCT7904D is designed for surface mount applications. It operates at a voltage of 3.3V and communicates via I²C/SMBus, making it suitable for various desktop and server systems.
