AS6221-AWLT-S

AS6221-AWLT-S is a digital temperature sensor. It is a high-accuracy digital temperature sensor system that communicates via a 2-wire digital bus with other devices. It consists of a Si bandgap temperature sensor, an ADC, and a digital signal processor. The high-temperature accuracy and ultra-low power consumption (low operation and quiescent current) make the AS6221 ideally suited for mobile/battery-powered applications. It is an easy-to-integrate and use solution, featuring a factory-calibrated sensor, integrated linearization, and the possibility to use 8 different I²C addresses, enabling to use of eight AS6221 devices on one bus. Additionally, the AS6221 temperature sensor system features an alert functionality, which triggers e.g. an interrupt to protect devices from excessive temperatures. Applications include fitness/health wristbands, personal computers, wearables, HVAC, replacement of PTCs, electronic equipment (tablets, convertibles, laptop).
