Fan Controller ICs
If your embedded design includes one or more fans, we offer a variety of fan controller ICs that will simplify your development and accelerate your time to market.
For embedded computing and PC applications, our integrated fan controllers offer built-in temperature sensors and look-up tables for setting the fan speed (PWM duty cycle) according to the measured temperature. If your system incorporates multiple fans,
we offer fan speed PWM controllers that include PID closed-loop control to better maintain fan set points through the entire life of the fan. They include algorithms for spin-up and ramp-rate control, making them a good fit for networking, mass storage
and server applications.
We also offer open-loop PWM fan controllers that use temperature-proportional fan speed control, making them well suited for telecommunications applications. They feature our FanSense technology to protect against fan and system failure, increase system
reliability and eliminate the need for three-wire fans.
