Fonctionnalités et applications

The TC670ECHTR is a part of TC670 Series Power Management Circuit. It can sustain a temperature ranging from -40 to +85°C, It comes in SOT-23-6 package.

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.
