*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under "Absolute Maximum Ratings" may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operation sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods may
affect device reliability.

DETAILED DESCRIPTION
TC623 Operation
The TC623 consists of a positive temperature coeffi-
cient (PTC) temperature sensor and dual threshold detec-
tor. Temperature set point programming is easily accom-
plished with external programming resistors from the HIGH
SET and LOW SET inputs to V
CC
. The HIGH LIMIT and LOW
LIMIT outputs remain inactive (low) as long as the measured
temperature is below setpoint values. As temperature in-
creases, the LOW LIMIT is driven high when temperature
equals the LOW LIMIT setpoint (
±
3
°
C). If temperature
continues to climb, the HIGH LIMIT output is driven high
when temperature equals the HIGH LIMIT setpoint (
±
3
°
C).
Figure 1 shows the relationship between the sense resis-
tance values and trip point temperature.
The CONTROL output is driven high when the HIGH
LIMIT output goes high, and is reset low when the LOW
LIMIT output goes low. This output provides the logic for
simple ON/OFF fan control. Figure 2 shows overall TC623
operation.
