ASC7521A
Description
The a SC7521A is a high-precision CMOS temperature sensor and voltage monitor with Simple Serial Transport (SST) patible serial digital interface, intended for use in PC hardware monitor applications. munication of device capabilities and temperature readings takes place over the high-speed bi-directional SST interface. The SST temperature sensor provides a means for an analog signal to travel over a digital bus enabling remote temperature sensing in areas previously not monitored in the PC. The temperature sensor supports an internal and external thermal diode. Sensor localization is aided by two address pins that distinguish multiple sensors on the same bus. The a SC7521A is available in MSOP-8 surface mount package.
