TC650BEVUA

The TC650BEVUA is a tiny integrated temperature sensor and brushless DC Fan Controller with over-temperature alert. The TC650 measures the junction temperature and control the speed of the fan based on that temperature, making it especially suited for applications in modern electronic equipment. Temperature data is converted from the on-chip thermal sensing element and translated into a fractional fan speed from 40 to 100%. A temperature selection guide in the data sheet is used to choose the low and high temperature limits to control the fan. The TC650 also includes a single trip point over-temperature alert that eliminates the need for additional temperature sensors. The TC650 is easy to use, require no software overhead and is therefore, the ideal choice for implementing thermal management in a variety of systems.

• Integrated temperature sensing and multi-speed fan control
• Temperature-proportional fan speed control for acoustic noise reduction and longer fan life
• Pulse width modulation (PWM) output drive for power savings
• Solid-state temperature sensing
• 50µA Typical low operating current
