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
3 the hysteresis control input (HSET) to VDD.
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 – 40°C to +125°C (TC07VxA). It features low (<130µA)
4 ^{supply current and small physical size 8-pin MSOP and}
8-pin SOIC packages, making it suitable for a wide variety
of applications.
