The MAX6672/MAX6673 are low-current temperature
sensors with a single-wire output. These temperature
sensors convert the ambient temperature into a 1.4kHz
PWM output, which contains the temperature informa-
tion in its duty cycle. The MAX6672 has an open-drain
output and the MAX6673 has a push-pull output.
The MAX6672/MAX6673 operate from 2.4V to 5.5V with
a maximum supply current of 150µA. Both devices fea-
ture a single-wire output that minimizes the number of
pins necessary to interface with a microprocessor.
The MAX6672/MAX6673 are available in 5-pin SC70
packages.
