MAX6672, MAX6673
PWM Output Temperature Sensors in SC70 Packages
Lowest Power PWM Output Temperature Sensors Available in SC70 Packages
|
Status
Active: In Production.
Description
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.
