Product Overview
The AMC6821SDBQ is an Intelligent Temperature Monitor and Pulse-Width Modulation (PWM) Fan Controller. Using either a low-frequency or a high-frequency PWM signal, this device can simultaneously drive a fan, monitor remote sensor diode temperatures and measure and control the fan speed so that it operates with minimal acoustic noise at the lowest possible speed. The AMC6821 has three fan control modes, auto temperature-fan mode, software-RPM mode and software-DCY mode. Each mode controls the fan speed by changing the duty cycle of a PWM output. All of the alarm thresholds are set through the device registers.
- Remote temperature sensor - ±2°C Accuracy, 0.125°C Resolution
- Local temperature sensor - ±2°C Accuracy, 0.125°C Resolution
- PWM controller
- 10 to 40kHz PWM frequency range
- 0% to 100%, 8-bit Duty cycle
