The TC670ECHTR from Microchip Technology is an integrated fan speed sensor that predicts and detects fan failure, preventing thermal damage to systems with cooling fans. It features fan wear-out detection for 2-wire linear-controlled fans and serves as a replacement system for 3-wire fans.
This device asserts an ALERT signal when the fan speed falls below a user-specified level. The fan alert level is set with a resistor divider on the THRESHOLD pin. The ALERT pin changes from high to low when the minimum fan speed is reached. This failure detection works with all linear-controlled 2-wire fans.
The TC670ECHTR operates over an industrial temperature range of -40°C to +85°C. It is available in a 6-pin SOT-23 package and consumes a low operating current of 90 µA (typical). The CLEAR capability allows for eliminating false alarms, providing flexibility in connecting the ALERT output with other system interrupts.
Applications include protection for linear-controlled fans in power supplies, industrial equipment, PCs and notebooks, data storage, data communications equipment, and instrumentation.
