TC670ECHTR Description

Short technical summary and product information.

The TC670ECHTR from Microchip Technology Inc. is an integrated fan speed sensor that predicts and detects fan failure, thereby preventing thermal damage to systems. It is designed for use with linear-controlled 2-wire fans and can serve as a replacement for 3-wire fan solutions.

Key features include fan wear-out detection, a fan alert signal that activates when fan speed drops below a programmed threshold, and a CLEAR capability for eliminating false alarms. The device operates with a low current consumption of 90 µA (typical) and supports a VDD range of 3.0V to 5.5V. The operating temperature range is specified from -40°C to +85°C.

The TC670ECHTR is housed in a compact 6-pin SOT-23 package, making it suitable for space-constrained applications. Its low power consumption and robust fan failure detection capabilities make it an ideal choice for various applications including power supplies, industrial equipment, PCs, notebooks, data storage, data communications equipment, and instrumentation.
