Controllers Sense System Temperature And Fan Faults

Adding to the company's extensive line of proprietary fan controllers, the TC652 and TC653 are claimed to be the first such devices capable of sensing both system temperature and fan-fault conditions. The devices integrate a temperature sensor and a brushless dc fan controller with the company's FanSense technology in an eight-pin MSOP. These new pulse-width modulation devices are said to greatly improve system reliability, reduce fan noise, extend fan life, and lower average operating current. They require no additional software and are suitable for a wide variety of applications, such as notebook and personal computers, set-top boxes, and networking equipment. Both devices drive any standard two-wire fan through a transistor or logic-level MOSFET and provide temperature-proportional, fan-speed control. The TC652 features a minimum fan speed setting and the TC653 has an auto shutdown mode. Prices start at $1.39 each/1,000.
