Integrated Circuit predicts fan failure.

TC670 detects critical fan speed of 2-wire and 3-wire fans and provides thermal failure protection in temperature-sensitive equipment. It predicts fan failure by sensing fan revolutions and asserting logic-low alert signal whenever fan speed falls below user programmable trip point. Single resistor divider is adequate for setting RPM alarm level, eliminating need for software. Unit also features...
