目录产品概述 返回TOP CXFA3161 is a single chip solution for fan speed control, packaged in a space saving SO-8 package. It connects directly to the fan and performs closed-loop control of the fan speed. The only external component required is a 10μF capacitor. It determined the current fan speed based on the fan rotation pulses and an externally supplied clock. It uses pulse width modulation (PWM) method and an on-chip MOSFET to control the fan speed to ±2% of the programmed speed. 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 this IC itself. An On/Off control pin is also provided.产品特点 返回TOP „Constant Fan Speed Control „PWM control for stable operation „Build-in MOSFET switch „SMBus interface „Internal short-circuit protection „On/Off control provided Appl 应用范围 返回TOP „Notebook PC „Industrial PC „LAN Switch „Servers „Telecom equipment „Industrial Control Gen 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！
