The TC620 is a 5V dual trip point temperature sensor from Microchip Technology, Inc., designed for thermal management applications. It features an onboard temperature sensor and provides dual thermal interrupt outputs (HIGH LIMIT and LOW LIMIT) that can be programmed using external resistors. The device operates within a temperature range of 0¬8C to 70¬8C, making it suitable for various applications, including power supply over-temperature detection and CPU thermal protection. The TC620 can be housed in either an 8-Pin PDIP or SOIC package, offering flexibility in design. Its user-programmable hysteresis and temperature set points enhance its adaptability for different thermal management needs.
TC620 and TC621 are programmable logic output temperature detectors designed for use in thermal management applications. The TC620 features an on-board temperature sensor, 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 program 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 simple ON/OFF control to a cooling fan or heater. The TC621 provides the same output functions except that the logical states are inverted. The TC620/621 are usable over a maximum temperature range of – 40C to +125C.
