MAX6672/MAX6673

PWM Output Temperature Sensors

in SC70 Packages

General Description

Features

● Simple Single-Wire PWM Output

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.

● Tiny SC70 Package

● Low 60µA (typ) Supply Current Consumption

● 1.4kHz Nominal Frequency

● Choice of Outputs

Open Drain (MAX6672)

Push-Pull (MAX6673)

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.

● 2.4V to 5.5V Supply Range

The MAX6672/MAX6673 are available in 5-pin SC70

packages.
