Microchip | TC620CEOA

Microchip Technology is a leading innovator and supplier of high performance and high quality embedded solutions and microcontrollers; related non-volatile memory products; and a broad analog product line focusing on power management, thermal management, linear and mixed-signal solutions.

Temperature sensing is critical to a growing number of consumer, automotive, and industrial applications. Microchip’s digital temperature sensors are ideal choice for implementing temperature system management schemes in a variety of applications.

TC620/TC621 - 5V Dual Trip Point Temperature Sensors

The TC620 and TC621 are programmable logic output temperature detectors designed for use in thermal management applications.

The TC620 features an onboard 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 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 TC621 provides the same output functions except that the logical states are inverted.

The TC620/TC621 are usable over operating temperature ranges of 0°C to 70°C, -40°C to +125°C and -55°C to 125°C.

The TC620CEOA is a SOIC (narrow) 5V Dual Trip Point Temperature Sensor with detection range from -40°C to +85°C.
