Description

The TC620CVOA belongs to TC620 and TC621 family which are programmable logic output temperature detectors designed for use in thermal management applications. The TC620CVOA 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 TC620CVOA, these outputs are driven active (high) when measured temperature equals the user-programmed limits. The CONTROL (hysteresis) output of TC620CVOA 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 TC620CVOA are usable over a maximum tempera- ture range of -40°C to +125°C.

The features of TC620CVOA can be summarized as (1)user-programmable hysteresis and temperature set point; (2)easily programs with 2 external resistors; (3)wide temperature detection range: -40°C to +125°C (TC620/621CVx); (4)external thermistor for remote sensing applications (TC621x).

The absolute maximum ratings of TC620CVOA are (1)package power dissipation (TA 70°C) PDIP: 730mW, SOIC: 470mW; (2)derating factors plastic: 8mW/°C; (3)supply voltage: 20V; (4)input voltage any input: (GND -0.3V) to (VDD +0.3V); (5)operating temperature: M Version: -55°C to +125°C, V Version: -40°C to +125°C, E Version: -40°C to +85°C, C Version: 0°C to +70°C.
