The TC670ECHTR is a predictive fan failure detector designed for use with 2-wire linear-controlled fans, providing a replacement solution for 3-wire fans. It monitors fan speed and asserts an ALERT signal when the speed falls below a user-defined threshold, which can be set using a resistor divider on the THRESHOLD pin. The device features a CLEAR function to reset the ALERT signal, minimizing false alarms and allowing integration with other system alerts. Operating over a voltage range of 3.0V to 5.5V, the TC670ECHTR has a typical supply current of 90 ¬µA and is housed in a compact 6-pin SOT-23 package. It is suitable for applications in power supplies, industrial equipment, PCs, notebooks, data storage, and data communications equipment. The device operates within an industrial temperature range of -40¬8C to +85¬8C, making it versatile for various environments.
