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.

-40°C to +85°C

-40°C to +125°C

0°C to +70°C

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

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.

-40°C to +85°C

NOTE: *The part code will be C or H.

(See Functional Block Diagrams).

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.
