General Description:
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 pro-
grammed with a single external resistor. On the TC620,
these outputs are driven active (high) when measured
Note:
*The part code will be C or H (see
Functional Block Diagrams).
temperature equals the user programmed limits. The
CONTROL (hysteresis) output is driven high when tem-
perature 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.
