Low-Voltage, 1.8kHz PWM Output Temperature

Sensors

General Description

Features

The MAX6676/MAX6677 are high-accuracy, low-power

temperature sensors with a single-wire output. The

MAX6676/MAX6677 convert the ambient temperature

into a ratiometric PWM output with temperature informa-

tion contained in the duty cycle of the output square

wave. The MAX6676 has an open-drain output and the

MAX6677 has a push-pull output.

ꢀ Operates from -4ꢂ5° to +12ꢀ5°

ꢀ Low 8ꢂµA ꢁypical °urrent °onsumption

ꢀ Small 6-Pin SOꢁ2± Package

The MAX6676/MAX6677 are specified for operation with

power-supply voltages from 1.8V to 3.6V, or from 3.6V to

5.5V (MAX6676 only). The typical unloaded supply cur-

rent is 80µA. All devices feature a single-wire output that

minimizes the number of pins necessary to interface

with a microprocessor (µP). The output is a square wave

with a nominal frequency of 1.8kHz (±±0ꢀ) at ꢁ±5ꢂ°.

The output format is decoded as follows:
