The MAX6577ZUT+T is a temperature sensor with period/frequency output in 6 pin SOT-23 package. This low cost, low current temperature sensor with a single wire output. It converts ambient temperature into a square wave with a period proportional to absolute temperature (°K). IC converts ambient temperature into a square wave with a frequency proportional to absolute temperature. It offers accuracy of ±3°C at +25°C, ±3.5°C at +85°C and ±4.5°C at +125°C. Device feature a single wire output that minimizes the number of pins necessary to interface with a microprocessor. The period/frequency range of output square wave can be selected by hard wiring the two time select pins (TS0, TS1) to either VDD or GND. It is used in critical μP and μC temperature monitoring, cell phones, battery packs, hard drives/tape drives and networking and telecom equipment.
Supply voltage range is 2.7V to 5.5V
