产品概述 返回TOP
The CXFA3165/CXFA3166 is a single chip solution for fan speed control. It can be directly connected to the fan and performs close-loop or open-loop control. And there are two modes, PWM and linear, to drive the fan. It determined the current fan speed based on the fan rotation pulses and an externally supplied clock. The desired fan speed is programmed via the SMBus. The actual fan speed and fan status can be read via the SMBus. Short-circuit protection is implemented to prevent damages to the fan and the IC itself.
