GENERAL DESCRIPTION
The TC07 is a programmable, logic output temperature
detector that operates from power supply levels as low as
2.7V. Programming is accomplished with external resistors
connected from the temperature setpoint input (T
SET
) and
the hysteresis control input (H
SET
) to V
DD
.
Complimentary outputs (OUT and OUT) are driven
active when temperature exceeds the temperature thresh-
old programmed by the resistor on T
SET
. The states of these
outputs are maintained (latched) until temperature falls
below threshold programmed by the resistor on H
SET
.
The TC07 is useful over a maximum temperature range
of 鈥?40擄C to +125擄C (TC07VxA). It features low (<130碌A)
supply current and small physical size 8-pin MSOP and
8-pin SOIC packages, making it suitable for a wide variety
of applications.
