产品概述

The MAX6634MSA+ is a 12bit plus sign temperature sensors with SMBus/I2C compatible serial interface in 8 pin NSOIC package. It combines temperature sensor, programmable overtemperature alarm and SMBus/I2C compatible serial interface in to a single package. The device converts its die temperature into digital values using internal ADC. The result of conversion is then held in a temperature register as a 12bit plus sign value which allows 0.0625°C resolution and can be readable at any time through serial interface. It is capable of reading temperatures up to 150°C. The MAX6634 has shutdown mode that saves power by turning off everything except power-on reset (POR) and serial interface. The MAX6634 has three address pins which allows up to eight devices to be connected to a single bus. The device incorporates dual mode active-low ALERT output (open drain) and can serve as an upgraded alternative to LM75 device. It is used in battery temperature alarms and PC temperature control.
  • Supply voltage range from 3V to 5.5V
  • Operating temperature range from -55°C to 150°C
  • Accuracy ±1°C (0°C to 50°C), ±1.5°C (-20°C to 85°C), ±2.5°C (-40°C to 125°C) and ±2.5°C (150°C)
  • User programmable temperature thresholds
  • User configurable alarm outputs and eight devices per bus
  • Ability to respond to SMBus/I2C compatible alert response address
  • Peak operating current of 270µA (VCC = 3V, SMBus inactive), 350µA (VCC = 5.5V, SMBus inactive)
  • Power supply rejection ratio of 0.2°C/V
  • Supply current of 12µA in shutdown (VCC = 3V, SMBus inactive) and 20µA (VCC = 5.5V, SMBus inactive)
  • Average operating current of 150µA (VCC = 3V, SMBus inactive) & 200µA (VCC = 5.5V, SMBus inactive)
