TC650 - (TC650 / TC651) Tiny Integrated Temperature Sensor & Brushless DC Fan Controller

General Description

The TC650/TC651 are integrated temperature sensors and brushless DC fan speed controllers.

The TC650/ TC651 measure their junction temperature and control the speed of the fan based on that temperature, making them especially suited for applications in modern electronic equipment.

Key Features

  • Integrated Temperature Sensing and Multi-speed Fan Control.
  • Built-in Over Temperature Alert (TOVER).
  • Temperature Proportional Fan Speed Control for Acoustic Noise Reduction and Longer Fan Life.
  • Pulse Width Modulation Output Drive for Cost and Power Savings.
  • Solid-State Temperature Sensing.
  • ±1°C (Typical) Accuracy from 25°C to +70°C.
  • 2.8V.
  • 5.5V Operating Range.
  • TC651 includes Auto Fan Shutdown.
  • Low Operatin.
