TC670 Tiny Predictive Fan Failure Detector Features General Description Fan Wear-Out Detection for 2-Wire The TC670 is an integrated fan speed sensor that Linear-Controlled Fans predicts and/or detects fan failure, preventing thermal damage to systems with cooling fans. When the fan Replacement System for 3-Wire Fans speed falls below a user-specified level, the TC670 Fan Alert Signal when Fan Speed is below asserts an ALERT signal. With this design, a critical Programmed Threshold minimum fan speed is determined by the user. The fan CLEAR Capability for Eliminating False Alarm alert level is then set with a resistor divider on the Low Operating Current, 90 A (typ.) THRESHOLD pin (Pin 1) of the TC670. When the V Range 3.0V to 5.5V minimum fan speed is reached, the ALERT pin (Pin 5) DD changes from a digital high to low. This failure detection Available in a 6-Pin SOT-23 Package works with all linear-controlled 2-wire fans. The TC670 Applications eliminates the need for 3-wire fan solutions. A CLEAR option can be used to reset the ALERT sig- Protection for Linear-Controlled Fans nal, allowing the flexibility of connecting the ALERT Power Supplies output of the TC670 with other ALERT/FAULT inter- Industrial Equipment rupts in the system. This feature can be implemented PCs and Notebooks so that false fan fault conditions do not initiate system Data Storage shutdown. Data Communications Equipment The TC670 is specified to operate over the full Instrumentation industrial temperature range of -40C to +85C. The TC670 is offered in a 6-pin SOT-23 pin package and Package Type consumes 90 A (typ.) during operation. The space- saving package and low power consumption make this SOT-23A-6 device an ideal choice for systems requiring fan speed monitoring.
