Product Summary
The AMC6821 is an intelligent temperature monitor and pulse-width modulation (PWM) fan controller. It is designed for noise-sensitive or power-sensitive applications that require active system cooling. Using either a low-frequency or a high-frequency PWM signal, the AMC6821 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 applications of the AMC6821 include Notebook and Desktop PCs, Network Servers, Telecommunications Equipment, PC-Based Equipment and DLP and LCD Projectors.
