GENERAL DESCRIPTION
The TC620 and TC621 are programmable logic output
temperature detectors designed for use in thermal manage-
ment applications. The TC620 features an on-board tem-
perature 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) out-
put 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 tempera-
ture range of – 40
°
C to +125
°
