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 information 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 feature 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.
