General Description

The AS6204 is a complete digital sensor system, designed for the needs of high-performance consumer electronics. It is based on the well-proven AS6200 design, but with additional I²C addresses to serve complex design needs. This is especially useful in the prototyping phase of a product where several heat sensitive areas might need monitoring but without needing to reserve additional systems application processor resources. The AS6204 is a fully calibrated and linearized sensor system that is easy to integrate in any digital system. It provides a resolution of 12 bit over the wide temperature range from -40°C to 125°C. The integrated alarm functionality enables micro-controller wake-up calls on defined temperature thresholds. An internal voltage regulator allows stable accuracy independent of the supply voltage between 1.8V to 3.6V. For powersensitive applications, the device can enter a low-power wait mode with 0.1μA current consumption.

This product suits for the following applications:

  • Laptops
  • Tablets
  • Solid State Disks
  • Industrial Automation
