MAX6575LZUT+T

The MAX6575LZUT+T is a temperature sensor with multidrop single-wire digital interface in 6 pin SOT-23 package. It is a low-cost, low-current temperature sensor with a single-wire digital interface. It features accuracy of ±3°C at +25°C, ±4.5°C at +85°C and ±5°C at +125°C. The MAX6575L is a monostable, externally triggered temperature sensor that allows a microprocessor (μP) to interface with up to eight temperature sensors using a single control line. Temperatures are sensed by measuring the time delay between the falling edge of the external triggering pulse and the falling edge of the subsequent pulse delays reported from the device. Different sensors on the same I/O line use different timeout multipliers to avoid overlapping signals. It features eight different timeout multipliers these are selectable by using the two time-select pins on each device. It provides four delays ranges less than 50ms.

• Supply voltage range is 2.7V to 5.5V
• Operating temperature range from -40°C to 125°C
• Timeout multipliers of 5μs/°K, 20μs/°K, 40μs/°K, 80μs/°K
• Simple single wire interface to μP or μC
• Low 150μA (typ) supply current
