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 set point
input (T_SET) and the hysteresis control input (H_SET) to
V_DD.
Complementary outputs (OUT and OUT) are driven
active when temperature exceeds the temperature
threshold 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 has an operating temperature range of -40°C
to +125°C (TC07VXA). It features low (<130μA) supply
current and with 8-pin MSOP and 8-pin SOIC
packages, making it suitable for a wide variety of
applications.
