DETAILED DESCRIPTION
The TC6501 through TC6504 integrate a temperature
sensor with a factory programmed threshold switch. A logic
signal is asserted when the die temperature crosses the
factory programmed threshold. An external hysteresis input
pin allows the user to select either 2
°C or 10°C hysteresis to
give further flexibility to the design of the application. The
TC6501 and TC6502 are intended for a temperature range
from 35
°C to 115°C in a 10°C increment. The TC6501 has
an open drain output and the TC6502 has a push /pull output
stage.
The TC6503 and TC6504 are intended for a cold
temperature range from –45
°C to +15°C in a 10°C incre-
ment.
The TC6503 has an open drain output and the
TC6504 has a push/pull output stage. The TC6501 and

TC6503 are intended for applications with a microprocessor
reset input. The TC6502 and TC6504 are intended for
applications of turning on a fan or heater element.
Hysteresis Input
To prevent the output from “chattering” at or near the trip
point temperature, a selectable HYST input pin is provided.
Hysteresis can be externally selected at 2
°C (HYST = GND)
or 10
°C (HYST = VDD) by means of the CMOS compatible
HYST input pin. Do not let the HYST pin float as this could
cause increase supply current. The hysteresis does not
depend on the part’s programmed trip threshold.

Thermal Considerations
With a very low 17
A supply current, the TC6501
through TC6504 dissipates very little power. Thus, the die
temperature is basically the same as the package tempera-
ture.
To minimize the error in temperature readings, the
load current should be limited to a few milliamps. As an
example, the typical thermal resistance of a 5-Pin SOT-23A
package is 140
°C/W. If for instance the TC6501 had to sink
