Temp Sensor Analog 8-Pin SOIC N Tube

The TC621 is programmable logic output temperature detectors designed for use in thermal management applications, while the TC621 connects to an external NTC thermistor for remote sensing applications. Both devices feature dual thermal interrupt outputs (HIGH LIMIT and LOW LIMIT), each of which is programmed with a single external resistor. The CONTROL (hysteresis) output is driven high when temperature equals the high limit setting and returns low when temperature falls below the low limit setting. This output can be used to provide ON/OFF control to a cooling fan or heater. The TC621 provides the same output functions except that the logical states are inverted. The TC621 are usable over operating temperature ranges of 0°C to 70°C, -40°C to +125°C and -55°C to 125°C.
