• Built-in 8-bit analog-to-digital converter (ADC)
• Monitors 4 analog voltage inputs, 2 fan tachometer inputs, and 2 remote temperature sensors
• Remote temperature sensor support for thermistor, transistor 2N3906, and CPU thermal diode
• Automatic fan speed control with PWM duty mode and linear mode support
• Internal oscillator and optional external clock input for accurate fan speed count
• Programmable upper and lower limits (alarm thresholds) for all monitored parameters
• Warning messages for system protection when monitored items exceed thresholds
• 2-wire I2C interface for communication with BIOS or application software
• Compatible with Fintek's MyGuard™ application software or other management software
• 4 general-purpose I/O support
• Powered by 3.3V and available in a 150 mil 16-pin SOP package
