TYPICAL APPLICATIONS
4.1
Over-Temperature Shutdown
The TC622 can be used to create a simple over-tem-
perature shutdown circuit. In this circuit, temperature is
sensed within the system enclosure (internal system
ambient) or at the heatsink itself. When measured
temperature exceeds a preset limit, a fault is indicated
and the system shuts down.
Figure 4-1 illustrates an over-temperature shutdown
circuit using the TC622 sensor in a single TO-220
package, allowing direct attachment to the heatsink
surface. As shown, the TC622 outputs are driven active
when the heatsink temperature equals the trip point
temperature set by RTRIP. When this happens, the
crowbar circuit is activated, causing the supply output
to fold back to zero. The TC622 outputs remain active
until the heatsink temperature falls a minimum of 2°C
(built-in hysteresis) below the trip point temperature, at
which time the device again allows normal supply
operation.
4.2
Cooling and Heating Applications
The TC622/TC624 can be used to control a DC fan as
shown in Figure 4-2. The fan turns on when the sensed
temperature rises above TSET and remains on until the
temperature falls below TSET - 2°C.
Figure 4-3 shows the TC622 acting as a heater
thermostat. Circuit operation is identical to that of the
cooling fan application.
