General Description
MAX6672 General Description
The MAX6672/MAX6673 are low-current temperaturesensors with a single-wire output. These temperaturesensors convert the ambient temperature into a 1.4kHzPWM output, which contains the temperature informa-tion in its duty cycle. The MAX6672 has an open-drainoutput and the MAX6673 has a push-pull output.
The MAX6672/MAX6673 operate from 2.4V to 5.5V witha maximum supply current of 150A. Both devices fea-ture a single-wire output that minimizes the number ofpins necessary to interface with a microprocessor.
The MAX6672/MAX6673 are available in 5-pin SC70packages.
