TC670 - Tiny Predictive Fan Failure Detector

General Description

The TC670 is an integrated fan speed sensor that predicts and/or detects fan failure, preventing thermal damage to systems with cooling fans.

When the fan speed falls below a user specified level, the TC670 asserts an ALERT signal.

Key Features

  • Fan Wear-out Detection for 2-Wire Linear Controlled Fans.
  • Replacement System for 3-Wire Fans.
  • Fan Alert Signal when Fan Speed is below Programmed Threshold.
  • CLEAR Capability for Eliminating False Alarm.
  • Low Operating Current, 90µA (typ. ).
  • VDD Range 3.0V to 5.5V.
  • Available in a 6-Pin SOT-23 Package General.

TC670 Tiny Predictive Fan Failure Detector Features • Fan Wear-out Detection for 2-Wire Linear Controlled Fans • Replacement System for 3-Wire Fans • Fan Alert Signal when Fan Speed is below Programmed Threshold • CLEAR Capability for Eliminating False Alarm • Low Operating Current, 90µA (typ.) • VDD Range 3.0V to 5.5V • Available in a 6-Pin SOT-23 Package General Description The TC670 is an integrated fan speed sensor that predicts and/or detects fan failure, preventing thermal damage to systems with cooling fans. When the fan speed falls below a user specified level, the TC670 asserts an ALERT signal. With this design, a critical minimum fan speed is determined by the user. The fan alert level is then set with a resistor divider on the THRESHOLD pin (Pin 1) of the TC670.
