TC620HCOA

The TC620 is programmable logic output temperature detectors designed for use in thermal management applications. The TC620 features an onboard temperature sensor. Both devices feature dual thermal interrupt outputs (HIGH LIMIT and LOW LIMIT), each of which is programmed with a single external resistor. On the TC620, these outputs are driven active (high) when measured temperature equals the user programmed limits. 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 TC620 are usable over operating temperature ranges of 0°C to 70°C, -40°C to +125°C and -55°C to 125°C.
